Overview
- Low Quiescent Current:
- 20μA in Active Mode;
- <2μA in Shutdown Mode
- Operates with a VIN as Low as 1.2V
- Low VCESAT Switch: 270mV at 300mA
- Uses Small Surface Mount Components
- High Output Voltage: Up to 30V
- Low Profile (1mm) ThinSOTTM Package
The ADPL21504 is a micropower step-up DC/DC converter in a 5-lead, low-profile (1mm) ThinSOT package. The ADPL21504 is designed for higher power systems with a 350mA current limit and an input voltage range of 1.2V to 15V. The ADPL21504 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 ADPL21504’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.
