DESCRIPTION

The MP163 is a primary-side regulator that

provides

accurate,

dual-output,

constant

voltage (CV) regulation without an optocoupler.

The MP163 supports buck, boost, buck-boost,

and flyback topologies and has an integrated

700V MOSFET and an LDO to simplify the

structure and reduce cost. These features make

the MP163 an ideal regulator for offline, low-

power applications, such as home appliances

and standby power.

The MP163 is a green-mode

operation

regulator. Both the peak current and switching

frequency decrease as the load decreases.

This feature provides excellent efficiency at light

load and improves overall average efficiency.

Full

protection

features

includ

e

thermal

shutdown, VCC under-voltage lockout (UVLO),

overload

protection

(OLP),

short-circuit

protection (SCP), and open-loop protection.
