TEXAS INSTRUMENTS UCC28701DBVT 控制器, 反激, 恒压, 恒流, 36V-9V电源, 130 kHz, SOT-23-6
Description
The UCC28700 family of flyback power supply controllers provides Constant-Voltage CV and Constant-Current CC output regulation without the use of an optical coupler. The devices process information from the primary power switch and an auxiliary flyback winding for precise control of output voltage and current. Low start-up current, dynamically controlled operating states and a tailored modulation profile support very low standby power without sacrificing start-up time or output transient response.
Features
• < 30-mW No-Load Power for 5-Star Rating
