完整的PWM电源控制、欠压闭锁电路内部、内部短路保护
DESCRIPTION
The incorporates on a single monolithic chip all the functions required for a pulse width modulation PWM control circuit. Designed primarily for power-supply control, It contains an error
amplifier, a regulator, an oscillator, a PWM comparator with a dead-time-control input, undervoltage lockout UVLO, short-circuit protection SCP, and an open-collector output transistor.
FEATURES
*Complete PWM power control
*3.6-V to 40-V operation
*Internal under voltage-lockout circuit
*Internal short-circuit protection
*Oscillator frequency : 20kHz to 500kHz
*Variable dead timer provides control over total range
