MP163
700V, Non-Isolated, Offline Regulator
with Integrated LDO
The Future of Analog IC Technology
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.
protection features includ
e
thermal
shutdown, VCC under-voltage lockout (UVLO),
overload
protection
(OLP),
short-circuit
protection (SCP), and open-loop protection.
