MP023 - Primary Side CC/CV Flyback Controller

General Description

The MP023 is an offline, primary-side controller that provides accurate, constant voltage and constant current regulation without the need of an optocoupler or secondary feedback circuit.

It uses an integrated 700V current source to achieve quick start-up.

Key Features

  • include VCC undervoltage lockout (UVLO), overload protection (OLP), over-temperature protection (OTP), open loop protection (OCkP), and over-voltage protection (OVP). The MP023's variable switching frequency method provides a natural spectrum for shaping a smooth EMI signature, which is suitable for offline, low-power battery chargers and adapters. The MP023 requires a minimal number of readily available, standard, external components and is available in a SOIC8-7A package.

MP023 Primary Side CC/CV Flyback Controller with High Voltage Current Source and The Future of Analog IC Technology Programmable Cable Compensation DESCRIPTION The MP023 is an offline, primary-side controller that provides accurate, constant voltage and constant current regulation without the need of an optocoupler or secondary feedback circuit. It uses an integrated 700V current source to achieve quick start-up. The MP023's variable off-time control allows its flyback converter to operate in discontinuous conduction mode (DCM). The MP023’s current limit and maximum secondary duty cycle are programmable, making the output current easily set. The FB voltage sensing point is also programmable and is able to set different switching frequencies.
