General Description
The APW7438A is a digitally controlled step-down regulator IC with an integrated 20mΩ high-side P-channel MOSFET and an 8mΩ low-side N-channel MOSFET. It features ANPEC's proprietary COT-mode control scheme for near-instantaneous correction to line/load transients for a voltage range of 2.7V to 6V, and 7A with constant frequency. The APW7438A is equipped with an automatic PFM/PWM mode operation. At light load, the IC operates in the PFM mode to reduce the switching losses and provides high efficiency over light to heavy loads with loading-modulated frequency. The APW7438A has an I2C serial interface port for output voltage margining and monitoring, if required (it can also operate in default mode). In addition it includes robust fault monitoring functions. The APW7438A is available in 0.8V default output voltage (no voltage divider is necessary) which can be changed from 0x01 Register.
