ADP8870ACBZ-R7

Overview

The ADP8870ACBZ-R7 is a charge pump-based LED backlight controller manufactured by Analog Devices Inc. It features seven independent outputs with a maximum output current of 60 mA per channel. The device operates on a supply voltage ranging from 2.5 V to 5.5 V and utilizes a boost topology to generate output voltages between 4.3 V and 5.1 V. It functions at a switching frequency of 1 MHz and is housed in an LFCSP-20 package. The component supports an operating temperature range from -40°C to +105°C.

Feature Summary

• Integrates a charge pump circuit for efficient LED backlight driving
• Provides seven individually controllable output channels
• Supports wide input voltage operation for flexible power design

Applications

• LED backlight drivers for medium-sized displays
• LED backlight drivers for large-sized displays
• White LED charge pump applications

Procurement Notes

Verify the specific suffix 'CBZ' against official Analog Devices documentation, as standard listings often reference the 'ACPZ' variant. Confirm availability status through authorized distributors, as stock levels may be restricted or subject to limited supply conditions. Ensure the selected package matches the required PCB footprint and thermal specifications for the target application.

Selection Notes

Select this component when designing systems requiring multiple independent LED strings driven by a single charge pump controller. Consider the 60 mA output limit per channel and the 1 MHz switching frequency for EMI management. Verify that the LFCSP-20 package dimensions fit within the available board space and that the operating temperature range meets environmental requirements.
