TPS54073 Overview
Key Specifications
Package: HTSSOP EP
Mount Type: Surface Mount
Pins: 28
Operating Voltage: 4 V
Description
As a member of the SWIFT™family of dc/dc regulators, the TPS54073 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 enables maximum performance and flexibility in choosing the output filter L and C components; an undervoltage-lockout circuit to prevent start-up until the input voltage reaches 3 V; an internally or 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 8-mΩ MOSFET Switches for High Efficiency at 14.5-A Peak Output Current
- Separate Low-Voltage Power Bus
- Disabled Current Sinking During Start-Up
- Adjustable Output Voltage Down to 0.9 V
- Wide PWM Frequency: Fixed 350 kHz, 550 kHz or Adjustable 280 kHz to 700 kHz
