产品说明

The LMR23630 SIMPLE SWITCHER® is an easy to use 36 V, 3 A synchronous step down regulator. With a wide input range from 4 V to 36 V, it’s suitable for various applications from industrial to automotive for power conditioning from unregulated sources. Peak current mode control is employed to achieve simple control loop compensation and cycle-by-cycle current limiting. The regulator’s quiescent current is 75 μA makes it suitable for battery powered systems. An ultra-low 2 μA current in shutdown mode can further prolong battery life. The switching frequency options allow either efficiency or solution size to be optimized. Internal loop compensation means that the user is free from the tedious task of loop compensation design. This also minimizes the external components of the device. The device has option for fixed frequency FPWM mode to eliminate frequency variation to minimize EMI. An extended family is available in 1 A and 2 A load current options in pin to pin compatible package which allows simple, optimum PCB layout. A precision enable input allows simplification of regulator control and system power sequencing. Protection features include cycle-by-cycle current limit, hiccup mode short circuit protection and thermal shutdown due to excessive power dissipation.
