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.
