DP2532
High Precision CC/CV Primary-Side PWM Controller
GENERAL DESCRIPTION
DP2532 is a high performance offline PWM
controller for low power AC/DC charger and
adapter applications. It operates in primary-side
sensing and regulation. Consequently,
opto-coupler and TL431 could be eliminated. High
Precision Constant Voltage (CV) and Constant
Current (CC) control are integrated as shown in
the figure below.
In CC control, the current and output power setting
can be adjusted externally by the sense resistor Rs
at CS pin. In CV control, multi-mode operations are
utilized to achieve high performance and high
efficiency. In addition, good load regulation is
achieved by the built-in Cable Drop Compensation.
Device operates in PFM in CC mode as well at
large load condition and it operates in PWM with
frequency reduction at light/medium load. The chip
consumes very low operation current, it can
achieve less than 80mW standby power.
DP2532 offers comprehensive protection coverage
with auto-recovery features including
Cycle-by-Cycle current limiting, VDD Over Voltage
Protection (VDD OVP), short circuit protection,
built-in leading edge blanking, VDD under voltage
lockout (UVLO), OTP, etc.
High precision constant voltage (CV) and constant
current (CC) can be achieved by DP2532.
DP2532 is offered in SOT23-6 package..
