PRODUCTION DATA
The LMR50410-Q1 converter is an easy-to-use synchronous step-down DC-DC converter operating from a 4-V to 36-V supply voltage. It is capable of delivering up to 1-A DC load current in a very small solution size. The family has multiple versions applicable to various applications. See Section 5 for detailed information.
The LMR50410-Q1 employs fixed-frequency peak-current mode control. The PFM version enters PFM Mode at light load to achieve high efficiency. A FPWM version is provided to achieve low output voltage ripple, tight output voltage regulation, and constant switching frequency at light load. The device is internally compensated, which reduces design time and requires few external components.
Additional features such as precision enable and internal soft start provide a flexible and easy-to-use solution for a wide range of applications. Protection features include thermal shutdown, VIN undervoltage lockout, cycle-by-cycle current limit, and hiccup mode short-circuit protection.
This family of devices requires very few external components and has a pin-out designed for simple, optimum PCB layout.
