S-8357N30MC-O2PT2G

Overview

The S-8357N30MC-O2PT2G is a positive output step-up boost DC-DC controller IC from ABLIC. It operates with an input voltage range of 0.9V to 10V and delivers a fixed 3.0V output. The device features a high switching frequency up to 600kHz and supports a maximum duty cycle of 85%. Packaged in a compact SOT-23-5 format, it is designed for efficient single-output applications.

Feature Summary

• Positive output step-up boost regulator topology
• Wide input voltage range supporting low-voltage sources
• High switching frequency capability for compact external components

Applications

• Single-output step-up power supply designs
• Battery-powered portable electronics requiring voltage boosting
• Low-voltage input systems needing stable 3.0V regulation

Procurement Notes

Verify the specific suffix O2PT2G against official ABLIC documentation to confirm pinout and electrical characteristics. Confirm RoHS compliance status through current datasheets. Check part status as some listings indicate 'Not For New Designs'. Ensure compatibility with required operating temperature ranges before procurement.

Selection Notes

Select this component when a fixed 3.0V output is required from inputs between 0.9V and 10V. The high switching frequency allows for smaller inductors and capacitors compared to lower-frequency alternatives. Consider the SOT-23-5 package constraints for PCB layout. Verify if the fixed output voltage meets system requirements without additional adjustment circuitry.
