Step-down converter

14 October 2015 Power Electronics / Power Management

Linear Technology’s LT8631 is a current mode PWM step-down DC-DC converter with internal synchronous switches that provide current for output loads up to 1 A. The wide input range of 3 V to 100 V makes it suitable for regulating power from a wide variety of sources, including automotive and industrial systems and 36 V to 72 V telecom supplies. Resistor programmable 100 kHz to 1 MHz frequency range and synchronisation capability enable optimisation between efficiency and external component size. The soft-start feature controls the ramp rate of the output voltage, eliminating input current surge during startup, while also providing output tracking. The IC’s shutdown mode reduces total quiescent current to below 5 A.
