Anpec APW7408B | Demoboard EVB_APW7408B

Description

The APW7408B is a 1.3A synchronous buck converter that uses current-mode control scheme to convert wide input voltage of 2.9V to 5.5V to outputs as low as 0.6V while providing excellent output voltage regulation.The APW7408B operates in Force PWM mode operation.The internal switching frequency is set at 1.4MHz while the EN/SYNC pin supports external clock synchronization, and is also equipped with Power-on-reset, internal soft start and complete protections (under-voltage, over-voltage,over temperature and current-limit) into a single low cost SOT-23-5 package. The IC also provides output capacitor discharge when it is disabled via the internal low side MOSFET.
