A7987TR, Switching Voltage Regulators 61 V 3A asynchronous step-down switching regulator adjustable current limit for
Semiconductors\Power Management ICs\Voltage Regulators & Voltage Controllers\Switching Voltage RegulatorsA7987 Step-Down Switching Regulators
STMicroelectronics A7987 Step-Down Switching Regulators deliver up to 3A DC with an output voltage adjustability of 0.8V to V IN. The A7987 meets industrial systems fail-safe specifications with a wide input voltage range and an almost 100% duty cycle capability. The embedded switch-over feature on the V BIAS pin maximizes the efficiency at light load. An adjustable current limitation is designed to select the inductor RMS current in accordance with the nominal output current. The high switching frequency capability makes the size of the application compact.
