APPLICATIONS
GENERAL DESCRIPTION
At light load, the IC operates in the PFM mode to reduce the switching losses. At heavy load, the IC works in PWM. At PWM mode, the switching frequency is set by the external resistor. The APW7153/A/B is also equipped with Power-on-reset, soft-start, soft-stop, and whole protections (under-voltage, over-voltage, over-temperature and current-limit) into a single package.
