The ZL2103 is an innovative power conversion and management IC that combines an integrated synchronous step-down DC/DC converter with key power management functions in a small package, resulting in a flexible and integrated solution.
The ZL2103 can provide an output voltage from 0.
54V to 5.
5V (with margin) from an input voltage between 4.
5V and 14V.
Internal low rDS(ON) synchronous power MOSFETs enable the ZL2103 to deliver continuous loads up to 3A with high efficiency.
An internal
Schottky bootstrap diode reduces discrete c...
