Texas Instruments Synchronous Buck DC/DC Converters
Texas Instruments LM5164-Q1 Synchronous Buck DC/DC Converters are AEC-Q100 qualified and have a wide input voltage range minimizing the need for external surge suppression.
The regulators can operate from a 6V to 100V input and have a minimum controllable on-time of 50ns. This enables large conversion ratios for reduced system complexity and cost, such as direct step-down from a nominal 48V automotive battery to low-voltage rails. The regulators integrate high- and low-side MOSFETs and can output up to 1A.
They feature an ultra-low quiescent current and offer high efficiency even at light loads by operating in diode emulation mode. The LM5164-Q1 has an adjustable switching frequency up to 1MHz and optimized for CISPR 25 EMI requirements.
