ADP5075ACBZ-R7

Overview

The ADP5075ACBZ-R7 is a high-performance DC-DC inverting regulator manufactured by Analog Devices Inc. It operates within an input voltage range of 2.85 V to 15 V and delivers up to 800 mA output current. The device generates adjustable negative outputs down to -39 V relative to the input. It features selectable switching frequencies of 1.2 MHz or 2.4 MHz, with external synchronization capability from 1.0 MHz to 2.6 MHz. The component utilizes a 12-pin WLCSP package and supports operation temperatures from -40°C to +125°C.

Feature Summary

• Integrated main switch capable of generating adjustable negative output voltages significantly below the input level
• Programmable slew rate control circuitry designed to minimize electromagnetic interference (EMI) noise
• External oscillator synchronization allows frequency adjustment between 1.0 MHz and 2.6 MHz for noise filtering
• Built-in safety mechanisms including overcurrent protection, overvoltage protection, thermal shutdown, and undervoltage lockout

Applications

• Powering bipolar amplifiers, ADCs, DACs, and multiplexers
• Providing bias supplies for charge-coupled devices (CCD)
• Supplying power to optical modules
• Biasing RF power amplifiers (PA)

Procurement Notes

Verify the specific suffix R7 indicates reel packaging when sourcing. Confirm the ACBZ designation matches the required WLCSP-12 footprint and temperature grade. Ensure the design accounts for the 800 mA continuous current limit and the wide input voltage compatibility. Cross-reference the datasheet for layout recommendations regarding the integrated MOSFET driver and feedback network components.

Selection Notes

Select this component for applications requiring a single-input dual-output negative rail generation without complex transformer designs. The fixed internal switch simplifies bill of materials compared to discrete solutions. Consider the 1.2 MHz/2.4 MHz options for balancing efficiency against passive component size. Verify that the 1.8 mA quiescent current aligns with system standby requirements.

Part Context

This part belongs to the ADP5075 series of dual-channel, high-performance DC-DC inverters. It is distinct from the ADP5076, which offers higher current capabilities and different topology configurations. The ADP5075 focuses on compact integration for generating precise negative rails from positive sources in space-constrained environments.
