DESCRIPTION

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,

over-

temperature protection, open circuit protection

(OCkP) and over-voltage protection. Its internal

high-voltage start-up current source and power-

saving 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.

The MP020-5 is available in SOIC8-7A.
