Overview

Low Quiescent Current:

20μA in Active Mode
<2μA in Shutdown Mode

Operates with a V_IN as Low as 1V
Low V_CESAT Switch: 95mV at 70mA

Uses Small Surface Mount Components
High Output Voltage: Up to 30V
Low Profile (1mm) ThinSOT^TM Package
Organic Light Emitting Diode (OLED) Power
Medical Diagnostic Equipment

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.
