Overview
The LM2792LD-H/NOPB is a dual-output DC-DC regulator utilizing switched capacitor (charge pump) topology, designed primarily for LED driver applications. It operates with an internal switching frequency of 1.1 MHz and supports both analog and PWM dimming control methods. The device is housed in a compact 10-WSON package measuring 3x3 mm. It functions within an operating temperature range of -30°C to 85°C and delivers a regulated output current of 34 mA per channel.
Feature Summary
- Integrates dual charge pump outputs for independent LED channel regulation
- Supports precise brightness control through combined analog and PWM dimming interfaces
- Utilizes high-frequency 1.1 MHz switching to minimize external component size
Applications
- LCD backlight power supply systems
- Dual-channel LED illumination circuits
- Portable electronic display drivers
Procurement Notes
Verify the specific suffix 'H' against the manufacturer's official datasheet to confirm pinout compatibility and thermal characteristics. Ensure the selected package variant matches the PCB footprint requirements. Cross-reference the RoHS compliance status with current regulatory standards before finalizing procurement orders.
Selection Notes
Select this component when a compact solution for dual LED strings is required without inductors. The 1.1 MHz frequency allows for smaller capacitors compared to lower-frequency alternatives. Consider the 34 mA output limit when sizing the LED load. Verify that the input voltage range aligns with the system power source capabilities.
Part Context
This part belongs to Texas Instruments' LM2792 family of LED drivers. It shares functional similarities with the LM2792LD-L/NOPB but differs in packaging or specific electrical ratings. The series focuses on simple, inductor-less power conversion for portable lighting applications requiring multiple regulated outputs.
Replacement Considerations
The LM2792LD-L/NOPB is a documented alternative within the same product family. Verify if the package type and specific electrical parameters meet the design requirements before substitution.
