The LMR23630-Q1 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
is 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. A quiescent current of 75 µA makes it suitable
for battery powered systems. Internal loop compensation means that the user is free from the
tedious task of loop compensation design. This also minimizes the external components. The device
has option for constant frequency FPWM mode to achieve small output voltage ripple at light load.
An extended family is available in 1 A (LMR23610-Q1), 1.5 A (LMR23615-Q1) and 2.5 A (LMR23625-Q1)
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.
