TPS54310 Overview
Key Specifications
Package: HTSSOP EP
Pins: 20
Operating Voltage: 6 V
Output Type (varies by manufacturer): Adjustable
Description
As a member of one of TI's families of dc/dc regulators, the TPS54310 low-input-voltage highoutput-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
- 1 60-mΩ MOSFET switches for high efficiency at 3A continuous output source or sink current
- Adjustable output voltage down to 0.9 V With 1% accuracy
- Externally compensated for design flexibility
- Fast transient response
- Wide PWM frequency: fixed 350 kHz, 550 kHz, or adjustable 280 kHz to 700 kHz
