S-8358N50MC-O7JT2U

Overview

The S-8358N50MC-O7JT2U is a boost DC-DC switching controller IC manufactured by ABLIC Inc. It operates within a supply voltage range of 0.9V to 10V and features a fixed switching frequency of 600kHz with a maximum duty cycle of 85%. The device provides a single positive output configured as a transistor driver. It is housed in an SC-74A (SOT-753) surface-mount package, specifically the SOT-23-5 supplier device outline. The component supports an enable control feature and functions without synchronous rectification or clock synchronization capabilities.

Feature Summary

• Boost topology for step-up voltage regulation
• Integrated enable control functionality
• Transistor driver output configuration

Applications

• Battery-powered portable electronics
• Low-voltage power management systems
• General-purpose DC-DC conversion circuits

Procurement Notes

Verify the specific suffix O7JT2U against official ABLIC documentation to confirm pinout and marking details. Ensure compatibility with the required 0.9V to 10V input range and 600kHz switching frequency. Confirm that the SOT-23-5 package aligns with PCB layout constraints. Cross-reference RoHS compliance status with current regulatory requirements before finalizing procurement orders.

Selection Notes

Select this component when a non-synchronous boost controller is required for space-constrained designs. The 600kHz frequency allows for smaller external passive components compared to lower-frequency alternatives. Verify that the load requirements do not exceed the internal switch limits inherent to the S-8358 series architecture. Ensure the application environment remains within the specified -40°C to +85°C operating temperature range.

Part Context

This part belongs to the S-8358 series of step-up switching regulator controllers from ABLIC. The series utilizes CMOS process technology designed for low-power applications. The N50 designation typically indicates a specific output voltage setting or feedback configuration within the broader product family, distinguishing it from other variants like the S-8358J or S-8358P series.

Replacement Considerations

Direct replacements within the same series include S-8358NxxMC-O7JT2U variants with different fixed output voltages. Other S-8358 series members such as S-8358F33MC-MKST2U share similar electrical characteristics but may differ in package type or specific output settings. Verify functional equivalence before substitution.
