Overview
The ISL97693IRTZ is a six-channel LED driver IC designed for battery-powered applications. It integrates six internal DC-DC boost regulator channels, each capable of delivering up to 30mA of output current. The device operates on a single or multiple cell Li-ion battery supply and supports PWM dimming with 12-bit resolution. It functions within a switching frequency range of 400kHz to 1.5MHz and is rated for an operating temperature range of -40°C to 85°C.
Feature Summary
- Integrates six independent DC-DC boost regulator channels for multi-zone LED control
- Supports high-resolution 12-bit PWM dimming for precise brightness adjustment
- Designed for direct operation from single or multiple cell Li-ion battery sources
Applications
- Backlight systems for portable electronic devices
- LED lighting solutions powered by Li-ion batteries
- Multi-zone LED indicator arrays in mobile equipment
Procurement Notes
Verify component authenticity through authorized Renesas distributors due to the prevalence of counterfeit power management ICs. Confirm that the package marking matches the specific suffix IRTZ to ensure correct tape-and-reel packaging and pin configuration. Check for recent Product Change Notifications regarding manufacturing site updates or label changes before finalizing procurement orders.
Selection Notes
Select this component when designing portable systems requiring independent control of up to six LED strings from a Li-ion source. Ensure the application demands 12-bit dimming resolution and fits within the 30mA per channel current limit. Verify that the external inductor and capacitor values support the 400kHz to 1.5MHz switching frequency range for optimal efficiency.
Part Context
This part belongs to the ISL976xx series of LED drivers from Renesas Electronics, formerly Intersil. The series targets portable consumer electronics and industrial lighting applications requiring efficient power conversion from battery sources. It complements other channel variants like the four-channel ISL97692 for different LED density requirements.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Consult Renesas technical support for cross-reference recommendations if this discontinued or end-of-life component is required.
