Optimized Typical Application for Minimal External Components Using ACT4088 28V, 1.5A, 1.4MHz Step-Down Converter

Optimized Typical Application for Minimal External Components Using ACT4088 28V, 1.5A, 1.4MHz Step-Down Converter. 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 components, and internal loop compensation provides simple, stable power supplies with a minimum of external components. Optimized for use with ceramic input and output capacitors, the ACT4088 provides a very compact 1.5A power supply for space constrained mobile and consumer applications
