MAX15157DATJ+

60V current-mode buck controller with lossless current sense. The MAX15157D implements a single-phase, PWM valley current-mode controller and drives two external power MOSFETs in a buck configuration. The output voltage can be dynamically set through the 1V to 2.2V reference input (REFIN) for modular design support. It features an adjustable internal compensation ramp. The device incorporates an accurate current-sense amplifier that reports output current through an analogue output (IMON). Suitable for datacentre, industrial, automotive and multiphase buck applications.
