MP023GS

MP023 Primary Side CC/CV Flyback Controller with High Voltage Current Source and Programmable Cable Compensation The Future of Analog IC Technology 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. The internal high-voltage start-up current source and power-saving technologies limit the no-load power consumption to less than 30mW. Full protection 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 maximum allowable continuous power dissipation at any ambient temperature is calculated by PD (MAX) = (TJ (MAX)-TA)/θJA. Exceeding the maximum allowable power dissipation produces an excessive die temperature, causing the regulator to go into thermal shutdown. Internal thermal shutdown circuitry protects the device from permanent damage. 3) The device is not guaranteed to function outside of its operating conditions. 4) Measured on JESD51-7, 4-layer PCB.
