TPS54233DR
2A , 28V输入,降压SWIFT ™ DC / DC转换器具有Eco-Mode ™ 2A, 28V INPUT, STEP DOWN SWIFT™ DC/DC CONVERTER WITH ECO-MODE™
DESCRIPON
The TPS54233 is a 28-V, 2-A non-synchronous buck converter that integrates a low Rdson high sideMOSFET. To increase efficiency at light loads, a pulse skipping Eco-mode™ feature is automatically activated. Furthermore, the 1 µA shutdown supply current allows the device to be used in battery powered applications.
