XC9288B35DER-G

Voltage Regulators - DC DC Switching Regulators Overview

The XC9288B35DER-G is a synchronous step-down DC/DC converter from the XC9288 series by Torex Semiconductor. It features HiSAT-COT control for stable operation with low-ESR ceramic capacitors. The device supports an input voltage range of 2.5V to 5.5V and provides a fixed output voltage of 3.5V at up to 1.5A output current. It integrates PWM/PFM auto-control, operates at a switching frequency of 3MHz, and includes shutdown functionality. The component is housed in a USP-C-EP-6 package and functions within a temperature range of -40°C to +105°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• HiSAT-COT control technology enables stable operation using only low-ESR ceramic output capacitors without requiring phase compensation adjustments.
• Integrated PWM/PFM auto-control optimizes efficiency across varying load conditions by automatically switching between pulse-width modulation and pulse-frequency modulation modes.

Voltage Regulators - DC DC Switching Regulators Applications

• Portable electronic devices requiring efficient power management
• Battery-powered equipment utilizing single-cell lithium-ion or lithium-polymer batteries
• Embedded systems needing regulated 3.5V supply rails

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'DER-G' against official Torex documentation to confirm package type and tape/reel specifications. Ensure compatibility with required operating temperatures and input voltage ranges for your application design before finalizing procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this part when a fixed 3.5V output is required from a 2.5V to 5.5V input source. The 1.5A current capability suits moderate load applications. Consider the 3MHz switching frequency for smaller external inductor sizes compared to lower-frequency alternatives.

Voltage Regulators - DC DC Switching Regulators Part Context

This component belongs to the XC9288 series of synchronous buck converters. The series is characterized by high integration, including built-in N-channel MOSFETs for both high-side and low-side switching, which reduces external component count and board space requirements.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Consult Torex Semiconductor's official cross-reference data for verified substitutes. Ensure any replacement maintains the same output voltage (3.5V), current rating (1.5A), and package footprint (USP-C-EP-6) for direct compatibility.
