Product Overview

The TPS5450EVM-254 is an evaluation module for TPS5450, a high output current PWM converter that integrates a low resistance high side N-channel MOSFET. The TPS5450 package along with the gate drive circuitry. The low drain to source on resistance of the MOSFET allows the TPS5450 to achieve high efficiencies and helps to keep the junction temperature low at high output currents. The compensation components are provided internal to the integrated circuit (IC), whereas an external divider allows for an adjustable output voltage. Additionally, the TPS5450 provides an enable input. The absolute maximum input voltage for the TPS5450 is 40V.
  • Input voltage range from 10V to 31V
  • Output current range up to 5A
  • 500KHz switching frequency
  • 18 µA Shut Down Supply Current
  • Improved line regulation and transient response by input voltage feed forward
  • System protected by overcurrent limiting, overvoltage protection and thermal shutdown
  • Internal compensation minimizes external parts count
  • High efficiency greater than 90% enabled by 110mΩ integrated MOSFET switch

Applications

Portable Devices, Imaging, Video & Vision, Power Management

Warnings

It is important to operate this EVM within the input voltage range of 10V to 31V and the output voltage range of 1.8V to 5V. Exceeding the specified input range may cause damage to the EVM.

A: 
Description:
TPS5450EVM-254 is an Evaluation module is designed to demonstrate a typical printed-circuit-board application using the TPS5450 regulator (Vin 10V - 31V, up to 5 A). This does not reflect the full range of possible input and output voltages that may be used when designing with this part. The switching frequency is internally set at a nominal 500KHz. The high-side MOSFET is incorporated inside the TPS5450 package along with the gate drive circuitry. The low drain-to-source on resistance of the MOSFET allows the TPS5450 to achieve high efficiencies and helps to keep the junction temperature low at high output currents. The compensation components are provided internal to the integrated circuit (IC), whereas an external divider allows for an adjustable output voltage. Additionally, the TPS5450 provides an enable input. The absolute maximum input voltage for the TPS5450 is 40V.
