产品概述

描述

This primary controller I.C., developed in BCD60II technology, has been designed to implement off line or DC-DC power supply applications using a fixed frequency current mode control. Based on a standard current mode PWM controller this device includes some features such as programmable soft start, IN/OUT synchronization, disable (to be used for over voltage protection and for power management), precise maximum Duty Cycle Control, 100ns leading edge blanking on current sense, pulse by pulse current limit, overcurrent protection with soft start intervention, and Standby function for oscillator frequency reduction when the converter is lightly loaded.
  • 所有功能

    • PRIMARY OVERCURRENT FAULT DETECTION WITH RE-START DELAY
    • PROGRAMMABLE SOFT START
    • IN/OUT SYNCHRONIZATION
    • PWM UVLO WITH HYSTERESIS
    • INTERNAL 100ns LEADING EDGE BLANKING OF CURRENT SENSE
    • LATCHED DISABLE
    • PACKAGE: DIP16 AND SO16
    • 100% AND 50% MAXIMUM DUTY CYCLE LIMIT
    • PROGRAMMABLE DUTY CYCLE
    • CURRENT-MODE CONTROL PWM
    • LOW START-UP CURRENT (< 120µA)
    • SWITCHING FREQUENCY UP TO 1MHz
    • FULLY LATCHED PWM LOGIC WITH DOUBLE PULSE SUPPRESSION
    • STANDBY FUNCTION
    • HIGH-CURRENT OUTPUT DRIVE SUITABLE FOR POWER MOSFET (1A)
