S-8358P20MC-O8FT2U

Overview

The S-8358P20MC-O8FT2U is a step-up switching regulator controller manufactured by ABLIC Inc. It operates within an input voltage range of 0.9V to 10V and delivers a fixed output voltage of 2.0V. The device utilizes a PWM control method with a typical switching frequency of 600kHz. It features a low quiescent current of 25.9uA and supports a maximum duty cycle of 85%. The component is housed in a compact SOT-23-5 package, suitable for surface mount applications across a temperature range of -40°C to +85°C.

Feature Summary

Integrates a high-efficiency step-up DC-DC converter controller optimized for battery-powered portable devices.
Employs a hybrid PWM/PFM control scheme to maintain stable regulation while minimizing power consumption during light load conditions.
Features a wide input voltage operating range compatible with single-cell lithium-ion batteries and alkaline cells.

Applications

Power management for mobile communication handsets
Supplying auxiliary voltages for handheld medical instruments
Boost conversion stages in portable consumer electronics

Procurement Notes

Verify the specific suffix O8FT2U against the official ABLIC datasheet to confirm pinout compatibility and thermal characteristics. Ensure the ordering quantity aligns with manufacturer reel specifications. Cross-reference the RoHS compliance status with current environmental regulations before finalizing procurement contracts.

Selection Notes

Select this component when a fixed 2.0V boost output is required from a variable input source. The 600kHz switching frequency allows for smaller external passive components compared to lower-frequency alternatives. Evaluate the 25.9uA quiescent current requirement against system standby specifications to ensure adequate battery life extension.

Part Context

This part belongs to the S-8358 series of switching regulators designed by ABLIC. The series focuses on low-power applications requiring efficient voltage boosting from single-cell sources. The S-8358 family shares common architectural features but varies in output voltage settings and control modes to suit diverse portable electronic needs.

Replacement Considerations

Direct substitutes include other S-8358 variants with different output voltages if the 2.0V setting is adjustable. Verify pin-to-pin compatibility with alternative manufacturers' boost controllers offering similar 600kHz frequencies and SOT-23-5 packaging.
