Overview
The ADP8870ACPZ-R7 is a charge pump-based LED backlight controller manufactured by Analog Devices Inc. It features seven independent output channels capable of delivering up to 60 mA per channel, designed for driving multiple LEDs in series or parallel configurations. The device operates on an input voltage range of 2.5 V to 5.5 V and utilizes I2C control for programmable settings. It employs a boost topology with a switching frequency of 1 MHz. The IC is housed in a 20-pin LFCSP package and supports an operating temperature range from -40°C to +105°C.
Feature Summary
- Integrates a charge pump circuit to drive high-voltage LED strings from low supply voltages
- Provides seven individually controllable current sources for flexible LED array management
- Supports digital configuration via standard I2C interface for dynamic brightness and fault monitoring
Applications
- Mobile phone LCD backlight systems
- Tablet computer display illumination
- Portable electronic device LED indicators
- Smartphone camera flash lighting
Procurement Notes
Verify the specific suffix R7 indicates reel packaging when sourcing components. Confirm that the ACPZ designation corresponds to the correct temperature grade and package variant required for your design. Ensure compatibility with existing I2C bus protocols and check for any recent manufacturing changes or lifecycle notices from Analog Devices before finalizing procurement plans.
Selection Notes
Select this component when designing systems requiring multi-channel LED driving with precise current control and digital adjustability. Consider the 1 MHz switching frequency for EMI management and the 60 mA output limit for LED string sizing. Evaluate the thermal performance within the LFCSP-20 package against the expected ambient conditions and power dissipation requirements of the target application.
Part Context
This part belongs to the ADP8870 series of LED drivers from Analog Devices, specifically tailored for portable consumer electronics. It complements other PMIC solutions by providing dedicated backlighting capabilities. The series is known for integrating protection features and efficient power conversion suitable for battery-operated devices where space and power efficiency are critical constraints.
