MP023GS Monolithic Power Systems

MP023 Primary Side CC/CV Flyback Controller with High Voltage Current Source and Programmable Cable Compensation The Future of Analog IC Technology DESCRIPTION FEATURES The MP023 is an offline, primary-side controller Primary-Side Control without Optocoupler or that provides accurate, constant voltage and Secondary Feedback Circuit constant current regulation without the need of Precise Constant Current and Constant an optocoupler or secondary feedback circuit. It Voltage Control (CC/CV) uses an integrated 700V current source to Variable Off-Time Peak Current Control achieve quick start-up. 700V High-Voltage Current Source The MP023 s variable off-time control allows its 20mW No-Load Power Consumption flyback converter to operate in discontinuous Programmable Cable Compensation conduction mode (DCM). The MP023s current Programmable Current Limit and Maximum limit and maximum secondary duty cycle are Secondary Duty Cycle programmable, making the output current easily Programmable FB Voltage Sensing Point set. The FB voltage sensing point is also Multiple Protection Features: OVP, OCkP, programmable and is able to set different OLP, OTP, VCC UVLO switching frequencies. Low Cost and Simple External Circuit The internal high-voltage start-up current Available in a SOIC8-7A Package source and power-saving technologies limit the APPLICATIONS no-load power consumption to less than 30mW. Full protection features include VCC under- Appliance Power Supplies voltage lockout (UVLO), overload protection Adapters for Handheld Electronics (OLP), over-temperature protection (OTP), Standby and Auxiliary Power Supplies open loop protection (OCkP), and over-voltage All MPS parts are lead-free, halogen-free, and adhere to the RoHS protection (OVP). directive.
