INFINEON ICE3BS03LJGXUMA1 PWM Controller

The ICE3BS03LJG is a high-performance, off-line PWM controller designed for low to medium power switch-mode power supplies. It features integrated 500V startup cell, active burst mode for ultra-low standby power, and advanced protections including latched off and auto restart modes. The controller offers frequency jittering to reduce EMI, an extendable blanking window for load jumps, soft-start to minimize stress during startup, and a wide VCC operating range up to 26V. Suitable for adapters, set-top boxes, and low-cost PSUs, it ensures high efficiency, system robustness, and minimal electromagnetic interference through modulated gate drive.
