 | Kit Overview
The Texas Instruments TPS5420EVM-175TPS5420EVM-175 evaluation module allows the designer to evaluate the TPS5420TPS5420 SWIFT DC/DC converter optimized for small size. The input voltage range of this module is 10 V to 36 V and the output voltage is pre-set to 5 V. The output voltage can be easily adjusted by changing a resistor divider. The multiProductLinkTPS5420 is ideal for a wide range of consumer electronics and industrial applications with an input voltage requirement of 5.5 V to 36 V.
The TPS5420TPS5420 dc/dc converter is designed to provide up to a 2-A continuous, 3-A peak output from an input voltage source of 5.5V to 36V. This evaluation module is designed to demonstrate the small printed-circuit-board areas that may be achieved when designing with the multiProductLinkTPS5420 regulator and does not reflect the high input voltages that may be used when designing with this part. The switching frequency is internally set at a nominal 500 kHz.
The high-side MOSFET is incorporated inside the TPS5420TPS5420 package along with the gate drive circuitry. The low drain-to-source on resistance of the MOSFET allows the multiProductLinkTPS5420 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 TPS5420 provides an enable input. The absolute maximum input voltage is 36V.
