Overview
The XC9504B093AR-G is a two-channel step-down and inverting DC/DC controller IC manufactured by Torex Semiconductor. It operates with an input voltage range of 2V to 10V and features a fixed switching frequency of 300kHz. The device supports adjustable output voltages from 1.5V to 15V with a maximum duty cycle of 80%. Designed for surface mount applications, it utilizes a 10-MSOP package and functions within a temperature range of -40°C to +85°C.
Feature Summary
- Dual-channel architecture supporting step-down and inverting topologies
- Fixed internal switching frequency for stable operation
- Adjustable output voltage capability across wide ranges
Applications
- Portable electronic devices requiring dual power rails
- Battery-powered systems needing efficient voltage conversion
- Embedded circuits utilizing step-down or inverting regulation
Procurement Notes
Verify the specific suffix 'G' indicates RoHS compliance when sourcing. Confirm the MSOP-10 package variant matches your PCB footprint requirements. Ensure the 300kHz switching frequency aligns with your electromagnetic interference constraints. Cross-reference the manufacturer datasheet for precise thermal dissipation guidelines during integration.
Selection Notes
Select this component when dual independent outputs are required from a single controller unit. The 300kHz frequency offers a balance between size and efficiency compared to lower frequencies. Consider the 10-MSOP package for space-constrained designs. Verify that the 2V to 10V input range covers your system's minimum battery voltage.
Part Context
This part belongs to the XC9504 series of switching controllers from Torex Semiconductor. It is distinct from the XC9504B092DR-G, which uses a USP-10 package and operates at 180kHz. The XC9504B093AR-G specifically targets applications requiring higher switching speeds and a different physical form factor than its series counterparts.
Replacement Considerations
The XC9504B092AR-G is a related model but differs in switching frequency (180kHz vs 300kHz) and maximum duty cycle (87% vs 80%). Direct substitution requires verifying if the frequency change impacts external component selection.
