Overview
The CL330SG-G is a three-channel linear LED driver IC from Microchip Technology, designed to drive three strings of LEDs at a constant current of 30 mA. It operates with an input voltage range of 6.5 V to 90 V and provides an output voltage range of 4 V to 90 V. The device features a fixed drive current with ±6% tolerance over a VOUT range of 4 V to 15 V. It includes PWM dimming, short circuit protection, and thermal protection. The component is housed in an 8-lead SOIC package with exposed pad (SOIC-8 EP) and supports surface mount installation.
Feature Summary
- Three independent channels for simultaneous LED string driving
- Supports PWM dimming and three-step linear dimming via separate enable pins
- Integrated short circuit and thermal protection mechanisms
- Fixed constant current output capability
Applications
- LED lighting systems requiring three-channel constant current drive
- General illumination applications utilizing PWM or linear dimming control
- Automotive or industrial LED modules operating within specified voltage ranges
Procurement Notes
Verify the specific ordering suffix 'SG' corresponds to the required tape and reel packaging configuration as indicated by distributor listings. Confirm that the 8-lead SOIC with exposed pad footprint matches the target PCB design. Ensure the supply chain source is authorized to guarantee compliance with RoHS directives and original manufacturer specifications. Cross-reference the datasheet revision date to confirm technical accuracy before finalizing procurement orders.
Selection Notes
Select this component when a three-channel linear LED driver with a 30 mA fixed output current is required. It is suitable for applications needing an input voltage range up to 90 V and support for PWM or linear dimming controls. Consider the SOIC-8 EP package constraints and the need for external components to set operating parameters if necessary. Verify that the thermal management requirements align with the device's protection features and operating temperature range.
Part Context
The CL330SG-G belongs to the CL320/CL325/CL330 family of 3-channel linear LED drivers manufactured by Microchip Technology. This family offers variants with different fixed current outputs: 20 mA for CL320, 25 mA for CL325, and 30 mA for CL330. All members share similar architectural features, including independent channel enables and protection circuits, allowing for scalable design across different LED brightness requirements.
Replacement Considerations
Direct substitutes within the same family include CL320SG-G for 20 mA applications and CL325SG-G for 25 mA applications. These parts share identical pinouts and functional characteristics, differing only in the fixed output current specification. Ensure the application can accommodate the lower current levels if substituting with CL320 or CL325 variants.
