ISL9443 controller equivalent, synchronous step-down pwm controller.
* Three Integrated Synchronous Buck PWM Controllers - Internal Bootstrap Diodes - Independent Programmable Output Voltage - Independent Soft-Starting and Tracking
Each output is adjustable down to 0.7V. The PWMs are synchronized at 180° out-of-phase, thus reducing the input RMS cur.
PIN 1 2 NAME ISEN1 VCC_5V FUNCTION Current signal input for PWM1. This pin is used to monitor the voltage drop across the lower MOSFET for current loop feedback and overcurrent protection. Output of the internal 5V linear regulator. This output supp.
