Cyh8116 Synchronous Step-up DC-DC Converter with Pfm Control IC Chip

DESCRIPTION:
The CYH8116 Series is a Synchronous step-up DC/DC Converter with PFM Control.With the CYH8116 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
