ACT4088 Description
The ACT4088 is a current-mode step-down DC/DC converter that supplies up to 1.5A into 5V from a 12V input. 1.4MHz switching frequency allows the use of tiny external ponents, and internal loop pensation provides simple, stable power supplies with a minimum of external ponents. Optimized for use with ceramic input and output capacitors, the ACT4088 provides a very pact 1.5A power supply for space constrained mobile...
