PWM BUCK CONTROLLER
General Description
The AP2008 integrates Pulse-Width-Modulation (PWM) control
circuit into a single chip, mainly designs for power-supply
regulator. All the functions include an on-chip 0.77V reference
output, an error amplifier, an adjustable oscillator, a soft-start,
UVLO, SCP circuitry, and a push-pull output circuit. Switching
frequency is adjustable by trimming CT. During low VCC situation,
the UVLO makes sure that the outputs are off until the internal
circuit is operational normally.
Applications
• Backlight inverter
• LCD Monitor
• XDROM, XDSL Product
• DC/DC converters in computers, etc.
