具有 PSR、NTC 选项和 150mV 电缆补偿功能的恒压、恒流 PWM 6-SOT-23 -20 to 125
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
• Primary-Side Regulation PSR Eliminates OptoCoupler
