MP020-5
Offline, Primary-Side Regulator
with CC/CV Control and a 700V FET
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.
