SSL4101T
GreenChip III+ SMPS control IC
• Using SSL4101T, a low power controller (< 50 mW) can be driven directly by the LED
lighting application power supply’s output while maintaining the input power in
Standby mode below the maximum of 0.5 W.
• Extremely high-efficiency can be achieved in LED lighting application power supplies
using the SSL4101T (between 92 % to 94 %). This enables the power supply to
operate reliably in enclosed spaces with very little cooling (which is typical for SSL
applications).
2. Features and benefits
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 switching losses (NXP Semiconductors patented).
Frequency reduction with fixed minimum peak current at low power operation to
maintain high efficiency at low output power levels.
2.5 Protection features
Safe restart mode for system fault conditions.
Continuous mode protection by means of demagnetization detection for both
converters (NXP Semiconductors patented).
UnderVoltage Protection (UVP) (foldback during overload).
Accurate OverVoltage Protection (OVP) for both converters (adjustable for flyback
converter).
Open control loop protection for both converters. The open loop protection on the
flyback converter is safe restart.
IC OverTemperature Protection (OTP).
Low and adjustable OverCurrent Protection (OCP) trip level for both converters.
General purpose input for latched protection, e.g. to be used for system
OverTemperature Protection (OTP).
