AP3021
AP3021 is PWM Controller manufactured by BCD Semiconductor.
Preliminary Datasheet
PWM Controller
General Description
AP3021 is a constant 330k Hz, voltage mode, external pensation boost controller. The IC has low reference voltage which makes it ideal for low cost LED backlight supplies. It can support DC dimming.
AP3021 employs plete protection to ensure system security. The device integrates Under Voltage Lockout, Over Voltage Protection, and Over Temperature Protection to protect the circuit.
To satisfy the requirements for small mounting space constraints, AP3021 is available in SOIC-8 package to save space.
