SSL4101T - NXP Semiconductors

SSL4101T GreenChip III SMPS controller

The GreenChip III+ is the third generation of green Switched Mode Power Supply (SMPS) controller ICs. The SSL4101T combines a controller for Power Factor Correction (PFC) and a flyback controller. Its high level of integration allows the design of a cost-effective LED lighting application power supply with a very low number of external components. The specia.

Features

2.1 Distinctive features „ Integrated PFC and flyback controller. „ True universal mains supply operation: 70 V (AC) to 305 V (AC). „ High level of integration, resulting in a very low external component count and a cost-effective design. 2.2 Green features „ On-chip start-up current source. 2.3 PFC green features „ Valley/zero voltage switching for minimum switching losses (NXP Semiconductors patented). „ Frequency limitation to reduce switching losses. „ PFC is switched off when a low load is detected at the flyback output. 2.4 Flyback green features „ Valley switching for minimum switchi.
