General Description
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 VCC situation, the UVLO makes sure that the outputs are off until the internal circuit is operating normally.

FEATUREs
• Dual PWM control circuitry
• Operating voltage can be up to 50V
• 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)

APPLICATIONs
• Backlight inverter
• DC/DC converts in computers, etc.
