XC9286B3CCER-G

Voltage Regulators - DC DC Switching Regulators Overview

The XC9286B3CCER-G is a synchronous buck converter from the HiSAT-COT series by Torex Semiconductor. It operates with an input voltage range of 2.5 V to 5.5 V and provides a fixed output voltage of 3.25 V at up to 1 A load current. The device features a switching frequency of 1.2 MHz and ultra-low quiescent current of 15 uA. It utilizes PWM/PFM auto control for efficiency optimization across varying loads. The component supports operation between -40°C and +105°C and includes shutdown functionality.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrates HiSAT-COT technology for stable operation without requiring phase compensation capacitors.
• Automatically switches between PWM and PFM modes to maintain high efficiency under light and heavy loads.
• Incorporates built-in N-channel driver FETs for synchronous rectification to minimize conduction losses.

Voltage Regulators - DC DC Switching Regulators Applications

• Portable electronic devices requiring efficient power management
• Battery-powered equipment with strict standby current constraints
• Embedded systems utilizing single-cell lithium-ion or lithium-polymer batteries

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'B3' confirms the fixed 3.25 V output voltage, as this family offers multiple fixed options. Confirm the 'CCER' package designation matches the required USP-C-EP-6 footprint for PCB layout compatibility. Ensure the '-G' suffix indicates RoHS compliance status according to the manufacturer's latest documentation before finalizing procurement specifications.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this part when a fixed 3.25 V rail is needed from a 2.5 V to 5.5 V source. The 1.2 MHz frequency allows for smaller external inductors compared to lower-frequency alternatives. Consider the 15 uA quiescent current for applications demanding minimal battery drain during sleep modes. Verify that the 1 A continuous output current meets the peak load requirements of the target circuit design.

Voltage Regulators - DC DC Switching Regulators Part Context

This component belongs to the XC9286 series of HiSAT-COT synchronous step-down DC/DC converters. The series is characterized by its ability to operate stably with low-ESR ceramic capacitors on both input and output sides. The B3 variant specifically denotes the fixed 3.25 V output configuration within the broader product line.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Check XC9286A3CCER-G for identical electrical performance in the same package. Verify XC9286B3ACER-G if a different package option is acceptable while maintaining the 3.25 V output.
