AP2001
MONOLITHIC DUAL CHANNEL PWM CONTROLLER
Features
General Description
• Dual PWM control circuitry
• Operating voltage can be up to 40V
• Adjustable Dead Time Control (DTC)
• Under Voltage Lockout (UVLO) protection
• Short Circuit Protection (SCP)
• Variable oscillator frequency: 500KHz Max
• 2.5V voltage reference output
• SOP-16L package
• Lead Free Finish/RoHS Compliant for Lead Free
products (Note 1)
The AP2001 integrates Pulse-width-Modulation (PWM) control
circuit into a single chip, mainly designed for power-supply
regulator. All the functions included are an on-chip 2.5V
reference output, two error amplifiers, an adjustable oscillator,
two dead-time comparators, UVLO, SCP, DTC circuitry, and dual
common-emitter (CE) output transistor circuit.
Recommend the output CE transistors as pre-driver for Driving
externally. The DTC can provide from 0% to 100%. Switching
frequency can be adjustable by trimming RT and CT. During low
V_CC situation, the UVLO makes sure that the outputs are off until
the internal circuit is operating normally.
Applications
• Backlight inverter
• DC/DC converts in computers, etc.
