Overview
The ISL97687IBZ-T is a four-channel DC-DC controller designed for LED backlight applications. It utilizes a boost topology and supports analog and PWM dimming methods. The device operates within a frequency range of 200kHz to 1.2MHz and provides an output current of 160mA per channel. It functions with a supply voltage between 9V and 32V. The component is housed in a 28-SOIC package and is rated for operation from -40°C to +105°C.
Feature Summary
- Four independent output channels for multi-zone LED control
- Supports both analog and pulse-width modulation dimming techniques
- Integrated boost converter topology for efficient power management
Applications
- LCD backlight systems
- LED lighting drivers
- Display illumination modules
Procurement Notes
Verify the specific suffix 'T' indicates tape-and-reel packaging, distinct from the tube-packaged ISL97687IBZ. Confirm end-of-life status as public records indicate discontinuation for this series. Ensure compatibility with existing PCB footprints for the 28-SOIC package before procurement.
Selection Notes
Select this component when designing high-efficiency LED backlights requiring precise multi-channel regulation. The wide operating frequency range allows optimization of external inductor size. Verify that the required dimming interface matches the available analog or PWM inputs provided by the controller architecture.
Part Context
This part belongs to the ISL97687 family of LED driver controllers manufactured by Renesas Electronics. The family focuses on providing robust power management solutions for display technologies. The IBZ designation specifies the standard plastic surface-mount package variant within this product line.
Replacement Considerations
Public records indicate the ISL97687 series has reached end-of-life status. No direct substitute part numbers are confirmed in available documentation. Designers should evaluate alternative LED driver ICs from other manufacturers that offer similar boost topologies and channel counts.
