ADP5076ACBZ-R7 General Description

The ADP5076 is a dual, high performance, dc-to-dc regulator that generates independently regulated positive and negative rails. The input voltage range of 2.85 V to 5.5 V supports a wide variety of applications. The integrated main switch in both regulators enables generation of an adjustable positive output voltage up to +35 V and a negative output voltage down to −30 V.

Key Features

Input supply voltage range: 2.85 V to 5.5 V
Generates well regulated, independently resistor programmable V_POS and V_NEG outputs
Boost regulator to generate V_POS output

Adjustable positive output to 35 V
Integrated 2.0 A main switch

Inverting regulator to generate V_NEG output

Adjustable negative output to −30 V
Integrated 1.20 A main switch

1.2 MHz or 2.4 MHz switching frequency with optional external frequency synchronization from 1.0 MHz to 2.6 MHz

Application

Bipolar amplifiers, ADCs, DACs, and multiplexers
Charge coupled device (CCD) bias supply
Optical module supply
