XC9501B095AR-G

Overview

The XC9501B095AR-G is a dual-channel step-up DC/DC controller manufactured by Torex Semiconductor Ltd. It operates with a fixed switching frequency of 180 kHz and supports a maximum duty cycle of 88%. The device provides two adjustable output voltage channels, ranging from 900 mV to 10 V, with a maximum output current capability of 500 mA per channel. It functions within an input supply voltage range of 2 V to 10 V and draws a typical operating supply current of 90 uA. The component is rated for operation between -40°C and +85°C and is housed in an MSOP-10 package.

Feature Summary

• Dual-channel architecture enabling independent control of two separate step-up power rails
• Fixed 180 kHz switching frequency to simplify external noise mitigation and filter design
• Low quiescent current consumption of 90 uA for improved system efficiency
• Adjustable output voltage range allowing flexible configuration for various load requirements

Applications

• Portable electronic devices requiring multiple regulated voltage rails
• Battery-powered systems needing efficient step-up conversion
• Embedded circuits utilizing single-cell lithium-ion or alkaline battery sources

Procurement Notes

Verify the complete part number including the suffix against official Torex Semiconductor documentation to ensure correct pinout and electrical specifications. Confirm that the required packaging format matches the specific order code variant. Cross-reference the manufacturing date code and RoHS compliance status with the supplier's certificate of conformity prior to finalizing procurement orders.

Selection Notes

Select this controller when a design requires two isolated step-up outputs from a single low-voltage source. Ensure the external inductor and capacitor values are calculated to support the 180 kHz frequency and 500 mA current limit. Verify that the input voltage range covers the minimum battery discharge curve of the target application.

Part Context

This component belongs to the XC9501 series of dual-channel step-up DC/DC controllers. The series is designed for applications requiring compact power management solutions with minimal external component count. The device integrates PWM control circuitry to maintain stable operation across varying load conditions.

Replacement Considerations

Consult the official Torex Semiconductor datasheet for confirmed substitute part numbers within the same product family. Verify compatibility regarding pin assignments, thermal characteristics, and electrical performance parameters before implementing any alternative components.
