Product information "RT2872GSP"

RT2872GSP, DC-DC Switching Buck Step Down Regulator, Adjustable, 4.5V-36Vin, 800mV-30Vout, 3Aout, 1MHz, SOP-8

The RT2872GSP is a highly efficient, current-mode synchronous step-down DC/DC converter in small 5 x 4 mm SOP8 package delivering up to 3A output current over a wide input voltage range from 4.5V to 36V. 

The device integrates 105mΩ high-side and 80mΩ low-side MOSFETs to achieve high conversion efficiency. The current-mode control architecture supports fast transient response and simple external compensation. With most commonly used input voltages between 5…28 V and output currents of 0.5… 2.5 A, the RT2872 efficiency is 85%+.   

A cycle-by-cycle current limit function provides protection against shorted output and an internal soft-start eliminates input current surge during start-up. The RT2872 provides complete protection functions such as input under-voltage lockout, output under-voltage protection, over-current protection and thermal shutdown. 

The RT2872 is available in the thermal enhanced SOP-8 (Exposed Pad) package.
