SSL4101T - GreenChip III+ SMPS controller

Description

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.

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 l.

SSL4101T GreenChip III+ SMPS control IC Rev. 1 — 21 April 2011 Product data sheet 1. General description 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 special built-in green functions provide high efficiency at all power levels. This applies to quasi-resonant operation at high power levels, quasi-resonant operation with valley skipping, as well as to reduced frequency operation at lower power levels. At low power levels, the PFC switches off to maintain high efficiency.
