EUP9287
Constant-Voltage, Constant-Current
Controller with Primary-Side Regulation
DESCRIPTION
The EUP9287 is a Constant-Voltage (CV) and
Constant-Current (CC) regulator controller with
primary side regulation. The device can control the
output voltage and current by sensing auxiliary
winding voltage.
EUP9287 operates in pulse width modulation mode
(PWM) or pulse frequency modulation mode (PFM)
automatically to keep the conversion efficiency high
across the line ranges.
The EUP9287 contains thermal shutdown function,
over-voltage protection and over-current protection.
