Monolithic Power Systems MP023GS
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).| Part No. | MP023GS |

DESCRIPTION
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 MP023 requires a minimal number of readily available, standard, external components and is available in a SOIC8-7A package.FEATURES
