S-8357H52MC-NNLT2U

Overview

The S-8357H52MC-NNLT2U is a positive output step-up DC-DC controller IC manufactured by ABLIC Inc. It operates within an input voltage range of 0.9V to 10V and provides a fixed output voltage of 5.2V. The device features a switching frequency of 250kHz and supports a maximum output current of 300mA. It functions reliably across a temperature range of -40°C to +85°C and is housed in a compact SOT-23-5 package.

Feature Summary

• Integrates a boost regulator for efficient positive output step-up conversion
• Supports wide input voltage ranges suitable for single-cell battery applications
• Utilizes a compact surface-mount package for space-constrained designs

Applications

• Portable electronic devices requiring stable power from single-cell sources
• Battery-powered equipment needing regulated higher voltage rails
• General-purpose step-up power management in consumer electronics

Procurement Notes

Verify the specific suffix NNLT2U against official ABLIC documentation to confirm package type and tape/reel specifications. Ensure compatibility with your PCB footprint, as SOT-23-5 dimensions are critical. Cross-reference RoHS compliance status directly with the manufacturer's latest datasheet before finalizing procurement orders.

Selection Notes

Select this component when a fixed 5.2V output is required from inputs ranging down to 0.9V. The 250kHz switching frequency offers a balance between efficiency and external component size. Consider the 300mA current limit for load requirements and ensure thermal management aligns with the SOT-23-5 package capabilities under expected operating conditions.

Part Context

This part belongs to the S-8357 series of switching controllers from ABLIC Inc., designed for low-power step-up applications. The series typically includes variants with different fixed output voltages and packaging options. It falls under the PMIC category, specifically targeting portable and battery-operated systems requiring reliable voltage regulation.

Replacement Considerations

Direct substitutes include other S-8357 series variants such as S-8357F50MC-MHJT2U for 5.0V output or S-8357G32MC-MIRT2U for 3.2V output, provided the voltage requirement differs. Verify pinout compatibility and electrical parameters before substitution.
