The LTC3872ETS8#PBF is a No RSENSE™ current mode boost DC/DC Controller drives an N-channel power MOSFET and requires very few external components. The No RSENSE™ architecture eliminates the need for a sense resistor, improves efficiency and saves board space. The LTC3872 provides excellent AC and DC load and line regulation with ±1.5% output voltage accuracy. It incorporates an under-voltage lockout feature that shuts down the device when the input voltage falls below 2.3V. High switching frequency of 550kHz allows the use of a small inductor. The LTC3872 can be used either by sensing the voltage drop across the power MOSFET or by connecting the SW pin to a conventional sensing resistor in the source of the power MOSFET.
● No current sense resistor required
● VOUT up to 60V
● Constant frequency 550kHz operation
● Internal soft-start and optional external soft-start
● Adjustable current limit
● Pulse skipping at light load
● ±1.5% Voltage reference accuracy
● Current mode operation for excellent line and load transient response
