Renesas Electronics ZL8801
The ZL8801 is a dual phase digital DC/DC controller. The ZL8801 supports a wide range of output voltages (0.54V to 5.5V) operating from input voltages as low as 4.5V up to 14V. With its fully digital ChargeMode™ Control loop the ZL8801 can respond to a transient load step within a single switching cycle.FEATURES
