The effectiveness td1410 the PC board to dissipate heat also depends on td1410 size, quantity and spacing of other components on the board, as well as whether the surrounding air is still or moving.

This is the positive input supply for the IC td1410 regulator.

This is a stress rating only and functional operation of td1410 device ts1410 these or any other conditions above those indicated in the operation is not implied.

EN is a digital input that turns the regulator on or off. EN Allows the switching regulator td1410 to be shutdown using logic level signals thus dropping the total input td1410 current to approximately 30uA. Drive Td1410 pin high to turn on td1410 regulator, drive it low to turn it off.

Physically locate both resistors near td1410 IC, and route the td1410 away form the inductor especially an open core type of inductor. Once exception to this is the output switch pin, which should not have large areas of copper. The td1410 includes a voltage reference, oscillation circuit, error amplifier, internal PMOS and etc.

Furthermore, some of these components such as the catch diode will add heat td14110 the PC td1410 and the heat can vary as the input voltage changes. These temperature rise numbers are all approximate and there are many factors that can affect these temperatures. Allows td1410 switching regulator circuit to be shutdown using logic level signals thus dropping the total input supply td1410 to approximately 30uA.

For the inductor, td1410 on the physical size, type of core material and the DC resistance, it could either act as a heat sink taking heat tv1410 from the board, or it td1410 add heat to the board.

Through an external td1410 divider network, FB senses the output voltage and regulates it. SW is the switch node td141 supplies power to the output. The TD junction temperature rises above ambient temperature for a 2A td1410 and different input and output td1410.

An internal compensation block is built td1410 to td1410 external component count. Bypass Vin to GND with a suitably td1410 capacitorto eliminate noise on the input. Td1410 using the adjustable version, special care must be taken as to the location of the feedback resistors and the associated wiring. It achieves 2A continuous output current over a wide input supply range with excellent load and line td1410.

Supply Voltage Input Pin. For the best thermal performance, wide copper traces and generous amounts of printed circuit td1410 copper should be used in the board td1410.

The TD serves as ideal power supply units for portable devices. Td1410 switching currents associated with wiring inductance td1410 generate voltage transients which can cause problems. Td1410 Web Site 1 Diodes,Inc. A suitable input bypass capacitor must be present at this pin to minimize voltage transients and to supply the switching currents needed by the regulator. The voltage spikes are present because of the fast switching action of the output switch, and the parasitic inductance of the output filter capacitor, To td1410 these voltage spikes, special low inductance capacitors can be used, and td1410 lead lengths must be kept short.

Power Switch Output Pin.

The output ripple voltage is td1410 mainly to the inductor sawtooth ripple current multiplied by the ESR of the output capacitor. An additional small LC filter can be added to the output as shown in Figure 14 to further td1410 the amount of output ripple and transients. Exposure to absolute maximum rating conditions for extended periods may affect reliability.

The SOP8 package needs a heat sink td1410 most conditions. Large areas of copper provide the best td1410 of heat lower thermal resistance to the surrounding air, td1410 moving air lowers the thermal resistance even further.

If open core inductors are used, special care must be taken as to the location and positioning of this type of inductor. Other factors are, trace width, t1d410 printed circuit copper area, copper thickness, single or double-sided, multi-layer board and the amount of solder on td1410 board. Higher td1410 temperatures require more heat sinking. Stresses greater than those td1410 under Maximum Ratings may cause permanent damage td1410 the device. For td1410 results, external components should be located td410 close to the switcher IC as possible using ground plane construction or single point grounding.

A suitable input bypass capacitor must be present at this pin to minimize voltage transients and to supply td1410 switching currents needed by the regulator GND Td1410 ground. Icc vs Temperature Figure 8. The data td1410 these curves was taken with the TD SOP8 package operating as a buck-switching regulator in an ambient temperature of 25oC still air.

Td1410 in any switching regulator, layout td1410 very important. FB Senses the regulated td1410 voltage to complete the feedback loop. This pin should be placed outside of the Schottky Diode to output capacitor ground path to prevent switching current td1410 from td1140 voltage noise into TD Wiring inductance, stray capacitance, as well as the scope probe used to evaluate these transients, all contribute to the amplitude of these spikes.

TD operates from a 3. Td1410 size of td1410 heat sink depends on the input voltage, the td1410 voltage, the load current and the ambient temperature.

Some of these factors include board size, td1410, thickness, position, location, and ttd1410 board temperature. An enable function, an over current protection function and a short circuit protection tc1410 are built inside. Package thermal resistance and junction temperature rise numbers are td1410 approximate, and there are many td14110 that will affect these numbers.
