DC DC Switching Controllers datasheet and documents for LTC3731CUH#TRPBF
DC DC Switching Controllers Overview
The LTC3731CUH#TRPBF is a three-phase synchronous buck controller manufactured by Analog Devices Inc. It operates with a switching frequency of 600kHz and accepts input voltages ranging from 4.5V to 32V. The device supports output voltages between 0.6V and 6V, utilizing a 24-pin SSOP package. Designed for industrial applications, it functions within an operating temperature range of -40°C to 85°C.
DC DC Switching Controllers Feature Summary
- Implements three-phase synchronous buck topology for high current delivery
- Integrates current-mode control architecture for precise regulation
- Supports adjustable switching frequencies up to 600kHz
DC DC Switching Controllers Applications
- Industrial point-of-load power supplies
- Distributed power systems requiring high efficiency
- Telecommunications infrastructure equipment
DC DC Switching Controllers Procurement Notes
Verify the specific suffix #TRPBF indicates tape and reel packaging configuration. Confirm that the CUH designation corresponds to the commercial temperature grade (-40°C to 85°C) and SSOP-24 package type. Ensure compatibility with external MOSFET selection for the intended load current requirements before finalizing procurement orders.
DC DC Switching Controllers Selection Notes
Select this component when designing multi-phase converters for high-current applications. The three-phase architecture allows for reduced input and output capacitance compared to single-phase solutions. Verify that the required output voltage falls within the 0.6V to 6V range and that the input supply does not exceed 32V.
DC DC Switching Controllers Part Context
This part belongs to the LTC3731 family of synchronous buck controllers. It is distinct from automotive-grade variants like the LTC3731CG which utilize different packages and temperature ratings. The CUH variant is optimized for general commercial and industrial use rather than specialized automotive environments.
DC DC Switching Controllers Replacement Considerations
Direct substitutes include other Analog Devices three-phase controllers such as the LT3731 series. Cross-reference pinouts and thermal characteristics carefully when replacing legacy components in existing designs.
