S-8357J50MC-NPJT2G

Overview

The S-8357J50MC-NPJT2G is a boost switching regulator IC from the ABLIC S-8357 series. It operates with an input voltage range of 900 mV to 10 V and provides a fixed output voltage of 5 V. The device features a switching frequency of 250 kHz and a maximum duty cycle of 78%. It supports a maximum output current of 300 mA and consumes a typical quiescent current of 18.7 uA. The component functions within a temperature range of -40°C to +85°C and is housed in a surface-mount SOT-23-5 package.

Feature Summary

• Integrates a synchronous rectifier structure for improved efficiency
• Utilizes CMOS process technology for low power consumption
• Includes built-in protection circuits against over-current and thermal issues

Applications

• Portable battery-powered electronic devices
• Consumer electronics requiring step-up voltage conversion
• Industrial control systems operating on low input voltages

Procurement Notes

Verify the complete part number including suffixes such as NPJT2G to ensure correct packaging and tape specifications. Confirm RoHS compliance status through official manufacturer documentation before integration. Check for recent production change notices that may affect pinout or electrical characteristics. Ensure supply chain sources provide original components with traceable manufacturing dates.

Selection Notes

Select this component when a fixed 5 V output is required from variable input sources between 0.9 V and 10 V. The 250 kHz switching frequency allows for smaller external passive components compared to lower frequency alternatives. Consider the 300 mA current limit for load requirements. The SOT-23-5 package suits space-constrained printed circuit board designs.

Part Context

This device belongs to the S-8357 series of DC-DC converters designed by ABLIC Inc. The series focuses on high-efficiency power management for portable applications. The S-8357 models typically integrate power switches and control logic into a single compact package, reducing external component count and board area.

Replacement Considerations

Direct substitutes include other ABLIC S-8357 variants with compatible output voltages and packages. Verify pin compatibility and electrical parameters before substitution. Cross-reference with similar boost regulators from other manufacturers only if pinouts and specifications match exactly.
