S-8358E20MC-NSFT2G

Overview

The S-8358E20MC-NSFT2G is a step-up switching regulator controller from ABLIC, designed for battery-powered applications. It operates within an input voltage range of 0.9V to 10V and delivers a fixed output voltage of 2.0V. The device integrates PWM/PFM control modes to optimize efficiency across varying load conditions. Key electrical characteristics include a typical quiescent current of 25.9uA and a switching frequency of 100kHz. It supports a maximum duty cycle of 90% and functions reliably within an ambient temperature range of -40°C to +85°C.

Feature Summary

• Integrates PWM/PFM hybrid control architecture to maintain high conversion efficiency under light and heavy load conditions.
• Features ultra-low standby current consumption suitable for portable devices requiring extended battery life.
• Includes built-in protection mechanisms against over-current and thermal overload to ensure operational safety.

Applications

• Battery-powered portable electronic devices
• Mobile communication equipment power management
• Consumer electronics with limited power budgets

Procurement Notes

Verify the specific suffix NSFT2G against official ABLIC documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with existing PCB footprints for the SOT-23-5 configuration. Cross-reference RoHS compliance status with the latest manufacturer declarations before finalizing procurement orders.

Selection Notes

Select this component when a fixed low-voltage output is required from a single-cell lithium-ion or alkaline battery source. The integrated controller reduces external component count compared to discrete solutions. Evaluate the 100kHz switching frequency against electromagnetic interference requirements in the target application environment.
