ESCRIPTION
PM2303 is a Boost constant current control
chip of QR mode; it can be used not only for
non-isolated applications, but also for
FLYBACK isolation applications. Multiple
patented technologies make it possible to
achieve high PF and low THD with very few
external components.PM2303 is mainly used in
constant current drive power supply system
with power less than 150W.
PM2303 can achieve high precision output
constant current under wide input, output
voltage and peripheral inductance parameters.
Combine QR mode and MOSFET drain
Voltage Valley-bottom opening technology to
achieve high efficiency and low
electromagnetic interference.
PM2303 integrates multiple protection
functions, such as output open circuit,
over-temperature protection, open circuit and
short circuit protection of all pins to make sure
LED driver more reliable.
PM2301 is packaged in SOP8.
