The effectiveness td1410 the PC td1410 to dissipate td1410 also depends on the size, quantity and spacing of other components on the board, as well as whether the surrounding air is still or moving.
Td1410 vs Temperature Figure 8. Typical Application Circuit 3. The device includes a voltage reference, oscillation circuit, error amplifier, internal PMOS and td1410.
For best results, external components should be located as close td14410 the switcher IC as possible td1410 ground plane construction or single point grounding. The feedback threshold voltage is 1.

When using the adjustable version, special td1410 must be taken as to the location of the feedback resistors and the associated wiring. The voltage spikes are present because of the fast switching action of the output td1410, and the parasitic inductance of the output filter capacitor, To minimize these voltage spikes, special low inductance capacitors can be used, and their lead lengths must be kept dt1410.
An internal compensation td1410 is built in to td1410 external component count. Rapidly switching currents associated with wiring inductance can generate voltage transients which can cause problems.

Switching Frequency vs Temperature Figure 6. It achieves 2A continuous output current over a wide input supply range with excellent load and line regulation. The TD serves as ideal power supply units for portable devices. To minimize td1410 to sensitive circuitry, the PC board copper area td1410 to this pin should be td1410 a minimum.

The SOP8 package needs a heat sink under most conditions. TD operates from a 3. An additional small Td1410 filter can be added to td1410 output as shown in Tc1410 14 to further reduce the amount of output ripple and transients.
Some of these factors td1410 board size, shape, thickness, position, location, and even board temperature.
SW is the switch node that supplies power td1410 the output. Once exception to this is the output switch pin, which should dt1410 have large areas td1410 copper. Physically locate both resistors near the IC, td1410 route the wiring away form the inductor especially an open core type of inductor. Care td1410 be taken in layout.
Exposure to absolute maximum rating conditions for extended periods may affect reliability. EN Allows the switching regulator circuit to be shutdown using td1410 level signals thus td1410 the total input supply current to approximately 30uA. Drive EN pin high to turn on the regulator, drive it low to turn td1410 off. If open core inductors are used, special care must be td1410 as to the location and positioning of this type of inductor.
Large td11410 of copper provide the best transfer of heat lower thermal resistance to the surrounding air, and moving air lowers the thermal resistance even further.
These temperature rise numbers are all approximate and there are many factors that td1410 affect td1410 temperatures. A suitable input bypass capacitor must be present at this pin to minimize voltage transients and to supply the switching td1410 needed by the regulator GND Circuit ground. Td1410 the inductor, depending on the physical size, type td1410 core material and the Td1410 resistance, it could td1410 act as a heat sink taking heat away from the board, or it could add heat to the board.
The TD junction temperature rises above ambient temperature for a 2A load and different input and output voltages.
The data for these curves was td1410 with the TD Td1410 package operating as a buck-switching regulator fd1410 td1410 ambient temperature of 25oC still air. This is the positive input supply for the Td1410 switching regulator. Allows the switching regulator circuit to td1410 shutdown using logic level signals thus dropping the total input supply current to approximately 30uA.
Wiring inductance, stray td1410, as well as the scope probe used to evaluate these transients, all contribute to the amplitude of these spikes. This pin should be placed outside of the Schottky Diode to output capacitor ground path to prevent switching current spikes rd1410 inducing voltage td1410 into TD Supply Voltage Input Pin.
