SG6848DZ1 General Description

This highly integrated PWM controller provides several special enhancements designed to meet the low standby-power needs of low-power SMPS. To minimize standby power consumption, the proprietary green-mode function provides off-time modulation to continuously decrease PWM frequency under light-load conditions. This green-mode function enables the power supply to easily meet even the strictest power conservation requirements.The BiCMOS fabrication process enables reducing the startup current to 5μA, and the operating current to 3mA. As a result, a large startup resistance can be used. Built-in synchronized slope compensation ensures the stability of peak-current-mode control. Proprietary internal compensation provides a constant output power limit over a universal AC input range (90VAC to 264VAC). Cycle-by-cycle current limiting ensures safe operation during short-circuits.To protect the external power MOSFET from being damaged by supply over voltage, the SG6848x1’s output driver is clamped at 15V. The SG6848x1’s controllers can be used to improve the performance and reduce the production cost of power supplies. The SG6848x1 is the best choice for replacing linear and RCC power supplies. It is available in DIP-8 and SSOT-6 packages.
