Overview
The S-8358B35MC-NQUT2U is a step-up switching regulator controller from ABLIC, designed for battery-powered applications. It operates within an input voltage range of 0.9V to 10V and provides a fixed output voltage of 3.5V. The device features a low quiescent current of 25.9uA and supports PWM/PFM control modes. It is housed in a compact SOT-23-5 package and functions reliably across a temperature range of -40°C to +85°C.
Feature Summary
- Integrates PWM/PFM control for optimized efficiency across load conditions
- Features ultra-low quiescent current for extended battery life
- Supports wide input voltage range suitable for single-cell lithium batteries
Applications
- Portable electronic devices requiring efficient power management
- Battery-operated sensors and IoT modules
- Consumer electronics with limited power budgets
Procurement Notes
Verify the specific suffix NQUT2U against official ABLIC documentation to confirm pinout and marking details. Ensure compatibility with external components such as inductors and diodes based on the 3.5V output requirement. Confirm RoHS compliance status through the manufacturer's latest environmental declaration before integration.
Selection Notes
Select this component when a fixed 3.5V output is required from a variable input source. Consider the 25.9uA quiescent current for standby applications. Verify that the SOT-23-5 package fits the PCB layout constraints. Compare with other S-8358 variants if different output voltages or switching frequencies are needed.
Part Context
This part belongs to the S-8358 series of step-up switching regulator controllers by ABLIC. The series is characterized by high-withstand voltage CMOS technology, enabling operation from low input voltages. It is designed for portable equipment where power efficiency and small footprint are critical design parameters.
Replacement Considerations
Check for direct substitutes within the S-8358 family with matching 3.5V output. Verify pin-to-pin compatibility with alternative manufacturers' boost controllers offering similar quiescent current and input voltage ranges.
