3.3V 1A: Low EMI: 92% Efficiency DC/DC Module in Single Layer TO-247 Form Factor Reference Design

Description

This reference design demonstrates a 15 mm x 20 mm: 92% efficiency: low electromagnetic interference (EMI) DC/DC module with TPS54202: replacing low dropout regulator (LDO) in major home appliance applications. The high efficiency eliminates the need of heat sink for a smaller and cheaper solution. The higher current capability enables additional features to be added (WiFi: sensors: etc ). The high efficiency and low-current consumption help achieve stringent energy ratings.

Features
  • 3.3-V regulated: up to 1A- output load92% efficiency2.3-μA standby current and 105-μA no load currentSmall form factor: size and pin-compatible and smaller than TO-247 (15 mm x 20 mm)Less than 32oC increase at full load: which eliminates the need of heat sinkReduce on-board DC/DC design complexity: save research and development time and efforts for switching power supply EMC design (quicker to market)
