Product Highlights
Accurate CC Regulation, Meets ±3 in a Typical
Design1
Controller Automatically Compensates For:
? Transformer inductance variation
? External component changes with temperature
? Input line voltage variations
This enhances production yield
Cost-Effective, Small Size Designs
? Eliminates the optocoupler and secondary CC control circuitry
? Eliminates control loop compensation circuitry
? Frequency-jitter greatly reduces EMI filter cost
? Programmable switching frequency reduces transformer size
? 725 V switching power MOSFET enables clampless flyback designs
Advanced Protection/Safety Features
? Auto-restart protection reduces power delivered by >90 for output
short-circuit and control loop faults (open and short-circuit components)
? Hysteretic thermal shutdown – with automatic recovery
? Meets high-voltage creepage requirements between DRAIN and all
other pins both on the PCB and at the package
EcoSmart?– Energy Efficient
? No-load consumption <30 mW1
? No current sense resistors – maximizes efficiency
Green Package
? All parts are halogen free and RoHS compliant
Applications
? LED bulbs, down lights, luminaires, ballasts and T8 tubes
Description
The LYTSwitch?-2 family of ICs dramatically simplifies low power CC
LED drivers by eliminating the optocoupler and secondary control
circuitry. The family introduces a revolutionary control technique which
provides accurate output current regulation, compensating for
transformer and external component variations, and device parameter
tolerances as well as input voltage variations.
The device incorporates a high-voltage switching MOSFET, an ON/OFF
control state-machine, a high-voltage switched current source for
self-biasing, frequency jitter to reduce EMI, cycle-by-cycle current limit
and hysteretic thermal shutdown circuitry into a monolithic IC. This high
level of integration enables cost-effective designs with very few
external components, reducing solution cost and driver size.
