MPS MP020-5GS-Z

Изолированный6,6 В ~ 28 В8 W

Overview

The MP020-5 is an offline, primary-side regulator that provides accurate constant voltage and constant current regulation without an opto-coupler or a secondary feedback circuit. It has an integrated 700V MOSFET. The MP020-5's variable off-time control allows a flyback converter to operate in discontinuous conduction mode. The MP020-5 also features protection functions such as VCC under-voltage lockout, over-current protection, overtemperature protection, open circuit protection (OCkP) and over-voltage protection. Its internal high-voltage start-up current source and powersaving technologies limit the no-load power consumption to less than 30mW. The MP020-5's variable-switching-frequency technology provides natural spectrum shaping to smooth the EMI signature, making it suitable for offline, low-power battery chargers and adapters.  FEATURES • Primary-Side–Control without Opto-Coupler or Secondary Feedback Circuit • Precise Constant Current and Constant Voltage Control (CC/CV) • Integrated 700V MOSFET with Minimal External Components • Variable, Off-Time, Peak-Current Control • 550µA High-Voltage Current Source • 30mW No-Load Power Consumption • Programmable Cable Compensation • Multiple Protections: OVP, OCP, OCkP, OTP, and VCC UVLO • Natural Spectrum Shaping for Improved EMI Signature • Low Cost and Simple External circuit • SOIC8-7A Package APPLICATIONS • Cell Phone Chargers • Adapters for Handheld Electronics • Stand-By and Auxiliary Power Supplies • Small Appliances
