TPS54372 Overview
Key Specifications
Package: HTSSOP EP
Pins: 20
Max Voltage (typical range): 6 V
Min Voltage (typical range): 3 V
Description
As a member of the SWIFT™ family of dc/dc regulators, the TPS54372 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 under transient conditions 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 and externally set slow-start circuit to limit in-rush currents; and a status output to indicate valid operating conditions.
Key Features
- Tracks Externally Applied Reference Voltage
- 60-mΩ MOSFET Switches for High Efficiency at 3-A Continuous Output Source or Sink Current
- 6% to 90% VI Output Tracking Range
- Wide PWM Frequency: Fixed 350 kHz or Adjustable 280 kHz to 700 kHz
- Load Protected by Peak Current Limit and Thermal Shutdown
