Overview
The S-8355M18BD-MCD-TFG is a step-up DC-DC controller IC manufactured by ABLIC Inc. It operates with an input voltage range of 0.9V to 10V and features a fixed switching frequency of 600kHz. The device supports a maximum duty cycle of 85% and provides a single positive output via a transistor driver stage. It is housed in a compact 6-SNB (1.8x2.0) surface-mount package and functions within a temperature range of -40°C to 85°C.
Feature Summary
- Integrated step-up topology for efficient voltage boosting applications
- Fixed 600kHz switching frequency for optimized external component sizing
- Wide input voltage capability supporting low-voltage sources down to 0.9V
Applications
- Battery-powered portable electronic devices requiring voltage elevation
- Low-input voltage systems needing regulated higher output rails
- Space-constrained designs utilizing small footprint controllers
Procurement Notes
Verify the specific suffix MCD against official ABLIC documentation to confirm pinout and marking variations. Confirm package type 6-SNB compatibility with your PCB layout. Check RoHS status and environmental compliance statements prior to integration. Ensure supply chain sources provide genuine components with traceable manufacturing data.
Selection Notes
Select this controller when a fixed-frequency boost solution is required with minimal external component count. Consider the 600kHz frequency trade-off between efficiency and passive size. Verify that the 85% maximum duty cycle meets the required input-to-output voltage ratio for your specific application constraints.
Part Context
