S-8358P20MC-O8FT2G

Overview

The S-8358P20MC-O8FT2G is a boost switching controller IC from ABLIC Inc., designed for step-up DC-DC conversion. It operates with an input voltage range of 0.9V to 10V and features a fixed switching frequency of 600kHz. The device utilizes PWM/PFM control modes and achieves a low quiescent current of 25.9µA. It provides a single positive output via a transistor driver stage without synchronous rectification. The component is housed in a compact SOT-23-5 package and supports operation across a temperature range of -40°C to +85°C.

Feature Summary

• Integrates PWM/PFM hybrid control mode for optimized efficiency across varying load conditions
• Features ultra-low quiescent current consumption to extend battery life in portable applications
• Supports wide input voltage range suitable for single-cell lithium-ion or alkaline battery systems
• Includes enable pin functionality for precise power management and system sleep control

Applications

• Portable electronic devices requiring efficient step-up power regulation
• Battery-powered sensor nodes and IoT modules
• LED driving circuits in low-power consumer electronics
• General-purpose boost converter designs in compact form factors

Procurement Notes

Verify the specific suffix O8FT2G against the manufacturer's latest datasheet to confirm marking codes and packaging details. Ensure compatibility with external MOSFET selection, as this is a controller rather than an integrated switch. Confirm RoHS3 compliance status through official Ablic documentation before finalizing procurement specifications.

Selection Notes

Select this component when a dedicated boost controller is required rather than an integrated regulator. Consider the 600kHz switching frequency for balancing component size and efficiency. Evaluate external inductor and diode ratings against the controller's drive capabilities. Verify that the application benefits from the low standby current characteristic compared to standard PWM-only controllers.
