Overview
The S-8357E15MC-NKAT2U is a switching controller manufactured by ABLIC Inc., designed for boost topology applications. It operates within an input voltage range of 0.9V to 10V and delivers a fixed output voltage of 1.5V. The device features a switching frequency of 300 kHz with a maximum duty cycle of 78%. It supports a maximum output current of 16.4 mA and maintains a low quiescent current of 25.9 uA. The component functions reliably across a temperature range of -40°C to +85°C and is housed in a compact SOT-23-5 surface-mount package.
Feature Summary
- Integrated boost switching controller optimized for step-up power conversion
- Low quiescent current consumption for extended battery life
- Fixed output voltage configuration ensuring stable regulation
Applications
- Battery-powered portable electronic devices
- Boost converter circuits requiring fixed low-voltage outputs
- Portable instrumentation and sensor systems
Procurement Notes
Verify the specific suffix NKAT2U against official ABLIC documentation to confirm pinout and marking details. Ensure compatibility with standard SOT-23-5 footprints during PCB layout. Confirm RoHS compliance status through the manufacturer's latest environmental declaration before final procurement approval.
Selection Notes
Select this component when a fixed 1.5V boost output is required from a wide input voltage range. The 300 kHz switching frequency allows for smaller external passive components compared to lower-frequency alternatives. Verify that the required load current does not exceed the specified 16.4 mA limit for reliable operation.
Part Context
This part belongs to the S-8357 series of switching controllers from ABLIC Inc. The series focuses on efficient power management solutions for portable electronics. These controllers are designed to drive external MOSFETs for DC-DC conversion, offering a balance between performance and power efficiency in a small form factor.
Replacement Considerations
Check for other S-8357 variants with different output voltages or current ratings if system requirements change. Verify pin-to-pin compatibility with existing designs before substituting.
