AP2004
PWM BUCK CONTROLLER
Features
General Description
• PWM Buck Control Circuitry
• Operating voltage can be up to 27V
• Under voltage Lockout (UVLO) Protection
• Short Circuit Protection (SCP)
• Soft-start circuit
• Variable Oscillator Frequency -- 300Khz Max
• 1.25V voltage reference Output
• 8-pin SOP package
• Lead Free Finish/ RoHS Compliant for Lead Free and
“Green” products (Note 1)
• SOP-8L: Available in “Green” Molding Compound (No
Br, Sb)
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.
