ZL8800ALAFT7A - Renesas Electronics

Description: The ZL8800 is a dual output or dual phase digital DC/DC controller. Each output can operate independently or be used together in a dual phase configuration for high current applications. The ZL8800 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 the fully digital ChargeMode™ control, the ZL8800 will respond to a transient load step within a single switching cycle. This unique compensation-free modulation technique allows designs to mee
