Overview
The PAM2701JER is a DC-DC regulator IC manufactured by Diodes Incorporated, designed for LED driver applications. It features four outputs with a current rating of 30mA per channel and operates on a switched capacitor (charge pump) topology. The device supports an input supply voltage range from 2.7V to 5.5V and includes internal switching elements. It functions at a frequency of 1MHz and offers analog voltage control for LED current dimming. The component is housed in a 16-QFN package measuring 3x3 mm with an exposed pad, suitable for surface mount installation.
Feature Summary
- Four-output DC-DC regulation capability using switched capacitor topology
- Analog voltage control interface for precise LED current dimming
- Integrated internal switches eliminating external inductor requirements
- Compact 16-pin QFN surface-mount packaging
Applications
- LED backlighting systems
- Portable electronic device illumination
- Low-power LED driver circuits
Procurement Notes
Verify the specific suffix JER against official Diodes Incorporated documentation to confirm package dimensions and tape-and-reel specifications. Confirm RoHS3 compliance status through the manufacturer's latest environmental statement. Check for obsolescence notices as this part may be discontinued. Ensure the supplier provides valid traceability documents matching the original manufacturer's batch codes.
Selection Notes
Select this component when designing LED drivers requiring multiple independent channels without magnetic components. The charge pump architecture suits space-constrained designs where inductors are undesirable. Verify that the required LED forward voltage falls within the achievable output range of the switched capacitor circuit. Ensure the application environment remains within the specified -40°C to 85°C operating temperature range.
Part Context
This part belongs to the PAM2701 series of LED driver ICs from Diodes Incorporated. These devices are engineered for portable electronics requiring efficient, compact power management solutions. The series utilizes charge pump technology to step up or regulate voltage for driving LEDs efficiently. This specific model represents a standardized surface-mount variant optimized for automated assembly processes.
Replacement Considerations
Consult Diodes Incorporated official cross-reference lists for verified substitutes. Generic equivalents may not match the 16-QFN footprint or analog control characteristics.
