S-8358H50MC-NVJT2U

Overview

The S-8358H50MC-NVJT2U is a step-up switching regulator controller from the ABLIC S-8358 series. It operates with a fixed output voltage of 5 V and supports an input supply range of 0.9 V to 10 V. The device features a high switching frequency of 600 kHz, enabling compact external component sizing. It incorporates PWM/PFM hybrid control for optimized efficiency across varying load conditions. Key electrical specifications include a maximum duty cycle of 85% and a quiescent current of 25.9 uA. The unit is housed in a SC-74A (SOT-753) surface-mount package and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Integrates PWM/PFM hybrid control logic to maintain high conversion efficiency under light and heavy load conditions.
• Features ultra-low standby current consumption suitable for battery-powered portable electronics.
• Supports synchronous rectification operation for enhanced power transfer efficiency.
• Includes built-in enable pin functionality for precise system power management.

Applications

• Battery-operated mobile devices requiring efficient voltage boosting
• Portable consumer electronics with strict power budget constraints
• Industrial instrumentation utilizing single-cell lithium-ion power sources

Procurement Notes

Verify the specific suffix NVJT against official ABLIC documentation to confirm tape-and-reel packaging and marking codes. Ensure compatibility with standard SOT-753 footprint designs. Cross-reference RoHS compliance status directly with the manufacturer's latest environmental declaration before finalizing procurement orders.

Selection Notes

Select this component when a fixed 5 V output is required from low-voltage inputs up to 10 V. The 600 kHz switching frequency allows for smaller inductors compared to lower-frequency alternatives. Consider the 25.9 uA quiescent current for applications prioritizing extended battery life over peak efficiency metrics.

Part Context

This part belongs to the S-8358 series of step-up switching regulators. The series is characterized by low standby current and flexible control modes. It serves as a core power management solution for applications needing reliable voltage regulation from single-cell batteries or low-voltage DC sources.

Replacement Considerations

Check ABLIC datasheets for variants sharing the S-8358 topology but differing in output voltage or package type. Verify pinout compatibility if substituting with other SOT-753 regulated controllers from different manufacturers.
