描述 Description

The uP9613 is a high-efficiency synchronous-rectified buck converter with an internal power switch. With internal low RDS(ON) switches, the high-efficiency buck converter is capable of delivering up to 2.3A output current for charger interface and a wide input voltage range from 10.8V to 32V. It operates in either CV (Constant Output Voltage) mode or CC (Constant Output Current) mode and provides a current limitation function. The uP9613 has a constant output voltage 5.2V/9.2V/12.3V for Quick Charge 2.0 ( QC2.0 ) that is detected from D+ and D- line and automatically detects whether a connected Powered Device (PD) is Quick Charge 2.0 capable before enabling output voltage adjustment. If a PD not compliant to Quick Charge 2.0 is detected, the uP9613 disables output voltage adjustment to ensure safe operation with legacy 5.2V only USB PDs.

Other features for the buck converter include internal softstart, adjustable external CC (Constant Output Current) limit setting, built-in fixed line-compensation, short circuit protection, VIN/VOUT over voltage protection, and over temperature protection. It is available in space saving PSOP-8L and VDFN6x5-8L packages.
