Description

The TI Design TIDA-00947 demonstrates a 10.5mmx14.5mm, 92% efficiency, low electromagnetic interference (EMI) DC/DC module with the TPS54202, replacing Low DropOut Regulator (LDO) in major home appliance applications. The high efficiency eliminates the need of heat sink for smaller and cheaper solution. The higher current capability enables additional feature to be added (WiFi, sensors, etc ). The high efficiency and low current consumption help achieving stringent energy rating.

Features
  • 3.3V regulated, up to 1A output load
  • 92% efficiency
  • 1.5μA standby current and 84μA no load current
  • Small form factor: size and pin-compatible and smaller than TO-220 (10.5mmx14.5mm)
  • Less than 31oC increase at full load, which eliminate the need of heat sink
  • Reduce the on-board DC/DC design complexity, save R&D time and efforts for switching power supply EMC design (quicker to market)
