Description

The ACE701CC Series is a Synchronous step-up DC/DC Converter with PFM Control. With the

ACE701CC Series, a step-up switching DC/DC converter can be configured by using an external coil,

capacitor. The built-in MOSFET is turned off by a protection circuit when the voltage at the LX pin exceeds

the limit to prevent it from being damaged
