Texas Instruments  LMR23630FQDRRTQ1

The LMR23630-Q1 SIMPLE SWITCHER® is aneasy-to-use 36-V, 3-A synchronous step-down regulator. With a wide input range from 4 V to 36 V,the device is suitable for various applications from industrial to automotive for powerconditioning from unregulated sources. Peak-current-mode control is employed to achieve simplecontrol-loop compensation and cycle-by-cycle current limiting. A quiescent current of 75 µA makesit suitable for battery powered systems. Internal loop compensation means that the user is freefrom the tedious task of loop compensation design. This also minimizes the external components. Thedevice has option for constant frequency FPWM mode to achieve small output voltage ripple at lightload. 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, optimumPCB layout. A precision enable input allows simplification of regulator control and system powersequencing. Protection features include cycle-by-cycle current limit, hiccup-mode short-circuitprotection, and thermal shutdown due to excessive power dissipation.
