Diodes Incorporated AP2004
The AP2004 integrates Pulse-Width-Modulation (PWM) control circuit into a single chip, mainly designs for power-supply regulator.FEATURES
● 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
● SOP-8L: Available in “Green” Molding Compound (No Br, Sb)
● Lead Free Finish/ RoHS Compliant (Note 1) AP2004 PWM BUCK CONTROLLER
GENERAL DESCRIPTION
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
