CS1630 /31

Overview

The CS1630 and CS1631 are high-performance offline AC /DC

LED drivers for dimmable and high color rendering index (CRI)

LED replacement lamps and luminaires. They feature Cirrus

Logic’s proprietary digital dimmer compatibility control technology

and digital correlated color temperature (CCT) control system that

enables two-channel LED color mixing. The CS1630 is designed

for 120VAC line voltage applications, and the CS1631 is

optimized for 230VAC line voltage applications.

The CS1630/31 integrates a critical conduction mode boost

converter, providing power factor correction and superior dimmer

compatibility with a primary-side regulated quasi-resonant second

stage, which is configurable for isolated and non-isolated

topologies. The digital CCT control system provides the ability to

program dimming profiles, such as constant CCT dimming and

black body line dimming. The CS1630/31 optimizes LED color

mixing by temperature compensating LED current with an

external NTC. The IC controller is also equipped with power line

calibration for remote system calibration and end-of-line

programming. The CS1630/31 provides a register lockout feature

for security against potential access to proprietary registers.
