Product Details
DESCRIPTION
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 control ler 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, over current protection with soft start
intervention, and Standby function for oscillator frequency
reduction when the converter is lightly loaded.
■ CURRENT-MODE CONTROL PWM
■ SWITCHING FREQUENCY UP TO 1MHz
■ LOW START-UP CURRENT (< 120µA)
■ HIGH-CURRENT OUTPUT DRIVE SUITABLE FOR POWER MOSFET (1A)
■ FULLY LATCHED PWM LOGIC WITH DOUBLE PULSE SUPPRESSION
■ PROGRAMMABLE DUTY CYCLE
■ 100% AND 50% MAXIMUM DUTY CYCLE LIMIT
■ STANDBY FUNCTION
■ PROGRAMMABLE SOFT START
■ PRIMARY OVERCURRENT FAULT DETECTION WITH RE-START DELAY
■ PWM UVLO WITH HYSTERESIS
■ IN/OUT SYNCHRONIZATION
■ LATCHED DISABLE
■ INTERNAL 100ns LEADING EDGE BLANKING OF CURRENT SENSE
■ PACKAGE: DIP16 AND SO16
