TPS54317 Overview
Key Specifications
Package: VQFN
Mount Type: Surface Mount
Pins: 24
Operating Voltage: 6 V
Description
As members of the SWIFT™ family of dc/dc regulators, the TPS54317 low-input-voltage high-output-current synchronous-buck PWM converter integrates all required active components. Included on the substrate with the listed features are a true, high performance, voltage error amplifier that provides high performance under transient conditions; an undervoltage-lockout circuit to prevent start-up until the input voltage reaches 3 V; an internally and externally set slow-start circuit to limit in-rush currents; and a power good output useful for processor/logic reset, fault signaling, and supply sequencing.
Key Features
- 2 60-mΩ MOSFET Switches for High Efficiency at 3-A Continuous Output Current
- Adjustable Output Voltage Down to 0.9 V With 1% Accuracy
- Switching Frequency: Adjustable From 280 kHz to 1600 kHz
- Externally Compensated for Design Flexibility
- Fast Transient Response
