Description 12V Synchronous Buck controller
Datasheet EM53T DatasheetEM5305 Datasheet (PDF)

12V Synchronous Buck controller General Description The EM5305 series are compact synchronous -rectified buck controllers specifically designed to operate from 5V or 12V supply voltage. The output voltage is tightly regulated to the external reference voltage from 0.4V to 3.0V. These devices operate at fixed 300 kHz frequency and provide an optimal level of integration to redwuce size and cost of the power supply. The controllers integrate internal MOSFET drivers that support 12V+12V bootstrappe.
