Micropower Step-Up DC/DC Converter

Overview

TopologyBoost Converter
Input voltage1-15 V
Output 130 V

Description

The ADPL21501 is a micropower step-up DC/DC converter in a 5-lead, low-profile (1mm) ThinSOT package. The ADPL21501 is designed for higher power systems with a 100mA current limit and an input voltage range of 1V to 15V. The ADPL21501 features a quiescent current of only 20μA at no load, which further reduces to 2μA (max) in shutdown. A current-limited, fixed off-time control scheme conserves operating current, resulting in high efficiency over a broad range of load currents.The 32V switch enables the generation of high voltage outputs up to 30V in a simple boost topology, eliminating the need for costly transformers. The ADPL21501’s low off-time of 400ns permits the use of tiny, low-profile inductors and capacitors, minimizing footprint and cost in space-conscious portable applications.
