LV5144RGYR TI Voltage Regulators - DC DC Switching Regulators
The LV5144RGYR is a dual-channel high-speed low-side gate driver from Texas Instruments, designed to drive MOSFET and IGBT switches. It features peak output currents of up to 4A source and sink, with independent enable pins for each channel. The device offers propagation delays of 18 ns and rise/fall times of 8 ns. Housed in a 14-pin VQFN package, it operates over -40°C to 125°C. Applications include switched-mode power supplies (SMPS), power factor correction (PFC) circuits, motor drives, and DC-DC converters requiring high peak current drive capability for high-frequency switching.
