S-8358N50MC-O7JT2G

Overview

The S-8358N50MC-O7JT2G is a boost switching regulator controller from ABLIC, designed for step-up DC/DC conversion. It operates within an input voltage range of 0.9V to 10V and delivers a fixed output voltage of 5.0V. The device features a high switching frequency of 600kHz and supports a maximum duty cycle of 85%. It includes an enable control feature and utilizes a single N-channel external MOSFET configuration without synchronous rectification. The component is housed in a compact SOT-23-5 package and functions reliably across a temperature range of -40°C to +85°C.

Feature Summary

• Integrates a 600kHz PWM/PFM hybrid switching controller for efficient power management
• Supports wide input voltage operation from 0.9V up to 10V
• Features an enable pin for precise power supply control and standby management

Applications

• Battery-powered portable electronic devices requiring step-up regulation
• Low-voltage sensor nodes needing stable 5V supply from single-cell sources
• General-purpose DC/DC converter designs in space-constrained PCB layouts

Procurement Notes

Verify the specific suffix O7JT2G against the manufacturer's latest datasheet to confirm marking codes and tape-and-reel specifications. Ensure compatibility with external components such as inductors and diodes rated for 600kHz operation. Confirm RoHS compliance status through official documentation before integration into regulated products.

Selection Notes

Select this controller when a fixed 5.0V output is required from variable or low input voltages. The 600kHz frequency allows for smaller passive components compared to lower-frequency alternatives. Verify that the external MOSFET can handle the peak currents generated by the boost topology at the intended load conditions.

Part Context

This part belongs to the S-8358 series of switching regulators from ABLIC Inc. The series focuses on high-efficiency step-up converters suitable for battery-operated applications. The S-8358N variant specifically provides a 5.0V output, distinguishing it from other models in the family that offer different fixed voltage levels.

Replacement Considerations

Direct replacements include other S-8358 series variants with compatible packages and electrical characteristics. Cross-reference with S-8358P52MC-O9LT2U for similar boost functionality but verify output voltage differences. Ensure any substitute maintains the 600kHz switching frequency and SOT-23-5 footprint.
