5V 1A, low EMI, 94% efficiency DC/DC module reference design using single-layer TO-247 package

TI reference design TIDA-00948 demonstrates a 15mmx20mm, 94% efficient low electromagnetic interference (EMI) DC/DC module using the TPS54202, replacing low dropout regulators (LDOs) in most appliance applications. High efficiency eliminates the need for a heat sink, resulting in a smaller, lower cost solution. Higher current capacity enables the addition of more functionality (WiFi, sensors, etc.). High efficiency and low current consumption help achieve stringent energy efficiency ratings.

characteristic

• ● 5V regulated voltage, output load up to 1A
• ● Efficiency up to 94%
• ● 2.5μA standby current and 89μA no-load current
• ● Compact size: size and pin compatible, smaller than TO-247 (15mmx20mm)
• ● The temperature rise is less than 30℃ at full load, no radiator is required
• ● Reduces onboard DC/DC design complexity, saving R&D time and effort in switching power supply EMC design (faster to market)
