Overview
The PQ6CU11X1APQ is a CMOS step-up chopper regulator manufactured by Sharp Microelectronics. It functions as an adjustable boost converter housed in a SOT-23-6 surface-mount package. The device supports an input voltage range up to 5.5V and provides a maximum output current of 0.25A (250mA). As a switching regulator, it utilizes a chopper stabilization technique to maintain regulation efficiency.
Feature Summary
- Integrates a CMOS step-up chopper regulator architecture for efficient voltage boosting.
- Features an adjustable output voltage configuration suitable for diverse power requirements.
- Utilizes a compact SOT-23-6 surface-mount package design.
Applications
- Battery-powered portable electronic devices requiring voltage step-up
- LED driver circuits utilizing constant current regulation
- General-purpose DC-DC conversion in space-constrained PCB layouts
Procurement Notes
Verify the specific manufacturer designation, as sources list both Sharp Corporation and Sharp Microelectronics. Confirm the exact electrical parameters against the official datasheet before integration. Ensure the SOT-23-6 footprint matches the target PCB design. Check for any recent product change notifications or lifecycle status updates from the supplier.
Selection Notes
Select this component when a low-profile, adjustable boost regulator is required for applications drawing up to 250mA. The SOT-23-6 package is suitable for high-density board designs. Consider the input voltage ceiling of 5.5V and the need for external passive components typical of chopper regulators during circuit design.
Part Context
This part belongs to the category of PMIC voltage regulators, specifically step-up converters. It serves as a power management solution for systems needing to elevate lower battery voltages to higher operational levels. The chopper regulator topology distinguishes it from standard PWM-based switching controllers.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Evaluate other Sharp Microelectronics boost regulators or generic CMOS step-up ICs with compatible SOT-23-6 footprints and similar current capabilities if direct substitution is required.
