ST1PS01CJR General Description

The ST1PS01CJR is a highly efficient and compact converter designed for applications that require a small PCB size and thickness. With the ability to dynamically select the output voltage from 0.625 V to 3.3 V using digital control inputs, this converter offers flexibility in various power supply designs. The use of enhanced PCC (peak current control) technology ensures high efficiency conversion with just a 2.2 µH inductor and two small capacitors, making it an ideal choice for space-constrained applications. Additionally, advanced circuitry design minimizes the quiescent current, further improving overall power efficiency. The Flip-Chip package option provides additional flexibility for integration into different systems and designs

Key Features
