LT8204RFE#PBF

LT8204RFE#PBF is a 40V full-bridge or dual half-bridge controller. It can be configured as either a four-switch full bridge controller or dual two-switch half-bridge controllers to regulate either the output voltage or the output current. It provides two selectable PWM control methods (i.e., peak current mode control and voltage mode control) to ease loop frequency compensation for applications with different load types (inductive, resistive, or capacitive loads). It features dual bidirectional rail-to-rail precision (200μV VOS) load current monitors, output voltage monitors, and dual on-chip 16-bit monotonic digital to-analogue converters (DACs). Together with the serial peripheral interface (SPI), the output current or voltage can be programmed precisely on-the-fly. It is used in applications such as solenoid and inductive load regulation, active or semi-active damping control, thermoelectric cooler (TEC) control, vibration control.
