General Description
CR623X is a high performance offline PWM
power switch for low power AC/DC charger
and adaptor applications. It operates in
primary-side sensing and provides constant
voltage (CV) and constant current (CC)
regulation without TL431 and opto-coupler.
A typical output CC/CV curve is shown as in
the Fig.1.

Program Cable Drop Compensation
Rich Protections For System Reliability
including
VDD Under Voltage Lockout with
Hysteresis (UVLO)
Cycle-by-Cycle Current Limiting
and Peak Current Protection (OCP)
Over Temperature Protection (OTP)
VDD Over Voltage Protection (OVP)
VDD Clamp
Lead-free SOP-8L & DIP-8L
Auxiliary Power for PC, TV etc.
Linear Regulator/RCC Replacement
In CC mode, the current point and maximum
output power setting can be adjusted by the
sense resistor RS at CS pin. In CV mode,
CR623X captures the auxiliary flyback
signal at Pin INV and then regulates the
output voltage. IN this mode, multi-mode
operations are utilized to achieve high
performance and high efficiency. In addition,
built-in cable drop compensation further
enhances output accuracy.
CR623X offers power on soft-start control
and ensures safe operation with complete
protections against all the fault conditions.
Built-in protection circuitry includes
Cycle-by-Cycle current limiting, peak current
protection, OTPVDD OVP, VDD clamp and
UVLO. Excellent EMI performance is
achieved with frequency jitter and soft-drive.
