The Future of Analog IC Technology
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.

Thermal Resistance (4) θJA θJC
SOIC8-7A .............................. 76 ...... 45... °C/W
Notes:
1) Exceeding these ratings may damage the device.
2) The maximum allowable power dissipation is a function of the
maximum junction temperature TJ (MAX), the junction-to-
ambient thermal resistance θJA, and the ambient temperature
TA. 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 will cause excessive die temperature, and the
regulator will 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.
