The LMR51420YDDCR from Texas Instruments is an easy-to-use, wide-input voltage synchronous buck converter capable of delivering up to 2A of load current. With an input voltage range from 4.5V to 36V, this device is well-suited for various industrial power conditioning applications from unregulated sources.
This converter operates at fixed switching frequencies of 500kHz and 1.1MHz, allowing for the use of smaller inductors and an optimized solution size. It is available in both PFM (for high efficiency at light loads) and FPWM (for constant frequency and low output ripple) versions. Internal compensation and soft-start circuits minimize the need for external components.
The LMR51420YDDCR includes built-in protection features such as cycle-by-cycle current limit, hiccup mode short-circuit protection, and thermal shutdown. It is housed in a compact SOT-23-6 Thin package, suitable for surface mount applications.
Key electrical specifications include a 4.5V to 36V input voltage range, a 2A continuous output current, and a maximum duty cycle of 98%. The operating junction temperature ranges from -40°C to 150°C.
