Overview
The S-8357B33MA-NIST2G is a Boost Regulator 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 3.3V. The device features a low quiescent current of 25.9µA and supports a maximum output current of 300mA. It utilizes PWM switching with a frequency of 250kHz and is housed in a compact SOT-23-3 package.
Feature Summary
- Integrates a high-efficiency boost converter controller for step-up voltage regulation
- Maintains ultra-low standby current consumption during operation
- Supports wide input voltage ranges suitable for single-cell battery applications
Applications
- Portable electronic devices requiring efficient power management
- Battery-powered systems utilizing single-cell lithium-ion sources
- Consumer electronics needing compact DC-DC conversion solutions
Procurement Notes
Verify the specific suffix NIST2G against the official datasheet to confirm the exact output voltage and package configuration. Ensure compatibility with the target PCB footprint for the SOT-23-3 package. Confirm RoHS compliance status through the manufacturer's latest documentation before finalizing procurement specifications.
Selection Notes
Select this component when a fixed 3.3V output is required from a variable or lower input source. The 250kHz switching frequency allows for smaller external passive components compared to lower-frequency alternatives. Consider the 300mA output limit to ensure it meets the peak load requirements of the downstream circuitry without exceeding thermal limits.
Part Context
This part belongs to the S-8357 series of switching controllers from ABLIC, designed for portable applications. It complements other variants in the family that offer different output voltages or packaging options. The series focuses on minimizing power loss in battery-operated devices while maintaining stable regulation under varying load conditions.
Replacement Considerations
Direct substitutes include other S-8357 series variants such as S-8357B33MA-NIST2G if pinout compatibility is critical. Verify electrical parameters like quiescent current and switching frequency against the original design requirements to ensure functional equivalence.
