The D36V6x family of buck (step-down) voltage regulators generates lower output voltages from input voltages as high as 50 V. They are switching regulators (also called switched-mode power supplies (SMPS) or DC-to-DC converters), which makes them much more efficient than linear voltage regulators, especially when the difference between the input and output voltage is large. This family includes seven versions with fixed output voltages ranging from 3.3 V to 15 V and two adjustable versions that can be set using a trimmer potentiometer:
Features
Connections
This regulator has four connections: shutdown (SHDN), input voltage (VIN), ground (GND), and output voltage (VOUT).
The SHDN pin can be driven low (under 1.25 V) to turn off the output and put the board into a low-power state (< 2 μA typical). The regulator is enabled by default, and this input can be left disconnected if you do not need this feature.
The input voltage, VIN, powers the regulator. Voltages between 4 V and 50 V can be applied to VIN, but for versions of the regulator that have an output voltage higher than 4 V, the effective lower limit of VIN is VOUT plus the regulator’s dropout voltage, which varies approximately linearly with the load (see below for graphs of the dropout voltage as a function of the load). Additionally, please be wary of destructive LC spikes (see below for more information).
