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. It features 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.
Applications & Description
• Dimmable Retrofit LED Lamps and LED Luminaries
• High CRI Lighting
• Offline LED Drivers
• Commercial Lighting
