Analog Devices ADPL26001

Low-IQ Boost/SEPIC/ Inverting Converter with 1A, 60V Switch

Overview

TopologyBoost Converter
Input voltage3.2-36 V
Output 160 V / 1 A

Description

The ADPL26001 is a current-mode DC/DC converter capable of generating either positive or negative output voltages using a single feedback pin. It can be configured as a boost, single-ended primary inductance converter (SEPIC), or inverting converter consuming as low as 6μA of quiescent current. Low ripple Burst Mode operation maintains high efficiency down to very low output currents while keeping the output ripple below 15mV in a typical application. The internally compensated current-mode architecture results in stable operation over a wide range of input and output voltages. Integrated soft-start and frequency foldback functions are included to control inductor current during start-up. The ADPL26001 comes in small package options that combined with a high switching frequency of 2MHz, helps to maintain a small footprint for an overall efficient, space-saving and cost-effective solution.
