Overview
The LT8710EFE#TRPBF is a synchronous PWM DC/DC controller supporting Boost, Inverting, and SEPIC topologies. It operates with an input voltage range of 4.5 V to 80 V and delivers up to 7 A output current. The switching frequency is adjustable from 100 kHz to 750 kHz. Quiescent current is 4 mA. It features rail-to-rail output current monitoring and control, along with input voltage regulation for high impedance inputs. The device is housed in a 20-lead TSSOP package with an exposed pad.
Feature Summary
- Supports multiple power supply topologies including Boost, Inverting, and SEPIC configurations.
- Provides rail-to-rail output current monitor and control capabilities.
- Includes input voltage regulation functionality designed for high impedance inputs.
Applications
- Industrial power supplies requiring wide input ranges
- Automotive electronics systems
- Telecommunications infrastructure equipment
Procurement Notes
Verify the specific suffix TRPBF indicates tape and reel packaging when ordering. Confirm the manufacturer part number matches Analog Devices Inc. specifications exactly. Ensure compatibility with the required 20-lead TSSOP footprint during PCB design. Check for RoHS compliance documentation if required by your manufacturing standards. Validate that the operating temperature range meets your environmental constraints.
Selection Notes
Select this component when a wide input voltage range up to 80 V is necessary. Choose it for applications requiring flexible topology support such as SEPIC or Inverting converters. Consider it for designs needing precise current monitoring without external shunts. Evaluate its suitability for high impedance input sources due to integrated regulation features.
Part Context
This controller belongs to the LT8710 series of synchronous PWM DC/DC controllers. It is manufactured by Analog Devices Inc., formerly Linear Technology.
