Overview
The S-8355M34MC-MCTT2G is a step-up switching regulator IC from ABLIC's S-8355 series, designed for portable applications. It operates with an input voltage range of 0.7V to 5.5V and provides a fixed output voltage of 3.4V. The device features a high-efficiency synchronous rectification topology and supports a maximum output current of 1.2A. It integrates a built-in power MOSFET and operates at a switching frequency of 1.2MHz. Key electrical parameters include a quiescent current of 1.6µA in standby mode and a shutdown current of 0.1µA. The unit is housed in a compact SOT-23-5 package.
Feature Summary
- Synchronous rectification architecture for high conversion efficiency
- Integrated low-noise LDO for stable operation
- Built-in soft-start circuit to limit inrush current
- Compact SOT-23-5 package design
Applications
- Portable electronic devices requiring efficient power management
- Battery-powered equipment utilizing single-cell lithium-ion or lithium-polymer sources
- Handheld instruments needing stable voltage regulation
Procurement Notes
Verify the specific suffix MCTT2G against official ABLIC documentation to confirm tape-and-reel packaging specifications and marking codes. Ensure compatibility with standard SOT-23-5 footprint designs during procurement planning.
Selection Notes
Select this component when a fixed 3.4V output is required from variable battery inputs. The integrated LDO feature makes it suitable for noise-sensitive analog sections within mixed-signal systems.
Part Context
This part belongs to the S-8355 series of step-up converters. It complements other variants in the lineup by offering a specific 3.4V output option with synchronous rectification capabilities for improved performance over non-synchronous alternatives.
Replacement Considerations
Check for direct pin-compatible substitutes within the S-8355 family that offer different output voltages if system requirements change. Verify thermal performance similarities when considering alternative packages.
