MP163
700V, Non-Isolated, Offline Regulator
with Integrated LDO
The Future of Analog IC Technology
DESCRIPTION
FEATURES
Primary-Side Constant Voltage (CV) Control,
Supporting Buck, Boost, Buck-Boost, and
Flyback Topologies
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.
Integrated 700V MOSFET and Current
Source
Internal LDO, Optimized for Dual Output
Applications
Less than 30mW of No-Load Power
Consumption
Up to 4W of Output Power
Low VCC Operating Current
Frequency Foldback
Limited Maximum Frequency
Peak-Current Compression
Internally Biased VCC
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.
Thermal Shutdown, UVLO, OLP, SCP, and
Open-Loop Protection
Full protection features include thermal
shutdown, VCC under-voltage lockout (UVLO),
Available in SOIC16 and SOIC8-7B
Packages
overload
protection
(OLP),
short-circuit
protection (SCP), and open-loop protection.
APPLICATIONS
