DESCRIPTION

The MP024-10 is a low-cost, offline, primary-

side, flyback regulator with a simple, external

circuit. It provides accurate constant voltage

(CV) and constant current (CC) regulation

without an optocoupler or secondary feedback

circuit and has an integrated 700V MOSFET

and high-voltage start-up current source.

The

MP024-10

operates

in

discontinuous

conduction mode (DCM) using variable off-time

control. Its power-saving technologies limit the

no-load power consumption to less than 30mW.

Full protection features include VCC under-

voltage

lockout

(VCC

UVLO),

overload

protection (OLP), over-temperature protection

(OTP), open-loop protection (OCkP), sensing-

short

protection

(SSP),

and

over-voltage

protection (OVP).

The

variable

switching

frequency

method

provides natural spectrum shaping to smooth

the EMI signature, making the MP024-10

suitable for offline, low-power battery chargers

and adapters.

The MP024-10 is available in a SOIC8-7B

package.
