S-8357B36MC-NIVT2G

Overview

The S-8357B36MC-NIVT2G is a step-up switching regulator controller from ABLIC, designed for efficient power management in compact electronic systems. It operates within an input voltage range of 0.9V to 10V and delivers a fixed output voltage of 3.6V. The device features a low quiescent current of 25.9uA, ensuring minimal power consumption during standby or light-load conditions. Operating at a switch frequency of 100kHz, it supports continuous conduction mode for stable performance. The component is housed in a small SOT-23-5 package, suitable for surface-mount applications across a temperature range of -40°C to +85°C.

Feature Summary

• Integrates a PWM control mechanism with a dedicated external N-channel MOSFET driver for efficient boost conversion.
• Maintains ultra-low quiescent current to extend battery life in portable devices operating under variable load conditions.
• Includes internal compensation circuitry to simplify external component selection and ensure loop stability.

Applications

• Battery-powered portable electronics requiring extended operational time
• Smartphones and mobile communication devices needing compact power solutions
• Wearable health monitoring devices with strict size constraints

Procurement Notes

Verify the complete part number including suffixes such as 'NIVT2G' against official ABLIC documentation to confirm specific tape-and-reel packaging and environmental compliance status. Ensure that the ordering information matches the exact electrical specifications required for your design, particularly regarding the fixed output voltage and package type. Cross-reference the manufacturer's latest datasheet to confirm any recent product change notifications or pinout revisions before finalizing procurement orders.

Selection Notes

Select this controller when a fixed 3.6V output is required from a single-cell lithium-ion battery source. The low quiescent current makes it suitable for applications where standby power efficiency is critical. Consider the SOT-23-5 package size if board space is limited. Ensure the external inductor and capacitor values are chosen to support the 100kHz switching frequency and provide adequate ripple filtering for sensitive downstream loads.

Part Context

This component belongs to the S-8357 series of switching regulators, which are optimized for low-power applications. The series offers various output voltage options and package types to accommodate different design requirements. As a controller rather than a full converter, it requires external power switches and passive components, providing designers with flexibility in optimizing efficiency and cost for specific system architectures.

Replacement Considerations

Direct substitutes may include other ABLIC S-8357 variants with compatible output voltages and packages. Verify pin compatibility and electrical parameters such as quiescent current and switching frequency when considering alternative models from different manufacturers. Ensure that any replacement maintains the same thermal performance and operating temperature range to avoid redesigning the PCB layout or cooling solution.
