ACT4088 Datasheet (Qorvo) - 1.4MHz Step-Down DC/DC Converter

ACT4088, 1.4MHz Step-Down DC/DC 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.
