The Infineon PWM controller suitable for lowest standby power and low EMI features with both auto restart and latch off protection features to enhance the system robustness. It targets for off Line battery adapters and low cost SMPS for low to medium power range. The inherited outstanding features includes 500V start up cell, active burst mode and propagation delay compensation, modulated gate drive etc. The newly added technology and features can further enhance the features. It includes BiCMOS technology, frequency jittering feature, built in soft start, built in blanking window with extendable blanking time for high load jump, external latch off enable pin, etc. Therefore, it is a versatile PWM controller for low to medium power application.
