Step-Down Voltage Regulator - Input Voltage 6.1 - 36V

The compact (13 x 18mm) D24V10F6 synchronous buck voltage regulator takes an input voltage of up to 36 V and efficiently reduces it to 6 V while allowing for a maximum output current of 1 A. This regulator offers typical efficiencies between 85% and 93% and has a very low dropout, so it can be used with input voltages as low as a few hundred millivolts above 6 V. The pins have a 0.1″ spacing, making this board compatible with standard solderless breadboards and perfboards

Pinouts

The buck regulator has five connections

• Power good (PG)
• Shutdown (SHDN)
• Input voltage (VIN)
• Ground (GND)
• Output voltage (VOUT)

The “power good” indicator, PG, is an open-drain output that drives low when the regulator’s output voltage falls below 80% or rises above 120% of its target output voltage. This output is also actively held low for the duration of the regulator’s 2 ms soft-start period and while the regulator is being disabled by the SHDN input or by over-temperature or over-current fault conditions. An external pull-up resistor is generally required to use this pin.

The SHDN pin can be driven low (under 0.4 V) to turn off the output and put the board into a low-power state. There is a 100 kΩ pull-up resistor between the SHDN pin and VIN, so if you want to leave the board permanently enabled, the SHDN pin can be left disconnected. While the SHDN pin is being driven low, the current draw of the regulator is dominated by the current through the pull-up resistor and will be proportional to the input voltage. (At 36 V in it will draw about 360 μA.)
