The ICE3B1565J is an offline SMPS Current Mode Controller with integrated 650V CoolMOS® and start-up cell. The CoolSET®-F3 (Jitter version) meets the requirements for offline battery adapters and low cost SMPS for the lower power range. By use of a BiCMOS technology a wide VCC range up to 26V is provided. This covers the changes in the auxiliary supply voltage if a CV/CC regulation is implemented on the secondary side. Furthermore an active burst mode is integrated to full-fill the lowest standby power requirements <100mW at no load and Vin = 270VAC. As during Active Burst Mode the controller is always active there is an immediate response on load jumps possible without any black out in the SMPS. In active burst mode the ripple of the output voltage can be reduced <1%. Furthermore auto restart mode is entered in case of over temperature, VCC overvoltage, output open loop or overload and VCC undervoltage.
