PWM BUCK CONTROLLER
General Description
The AP2004 integrates Pulse-Width-Modulation (PWM) control
circuit into a single chip, mainly designs for power-supply
regulator. All the functions include an on-chip 1.25V 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 operates normally.
Applications
• Backlight inverter
• LCD Monitor
• CDROM, XDSL Product
• DC/DC converters in computers, etc.
