Product description: D24V22F3 - Step-down converter - 3.3V 2.6A - Polyol 2857.

A step-down converter (buck) used to power systems operating at 3.3 V. The advantage of the system is a wide range of input voltages from 4.0 V to 36 V. D24V25F5 module allows for current consumption up to 2.6 A.

D24V22F3 inverter outputs

Pin Description
VIN Input voltage.
GND Mass potential.
VOUT Output voltage.
ENABLE If a low-voltage state below 1 volt is given), the system will go into a low power consumption state (approx. 10 μA). The pin is pulled to the supply voltage through a 270 kΩ resistor, which makes the system switched on by default.
PG Pin "Power Good" open-drain. It goes into a low state when the output voltage drops below 85 % of its nominal value. If this pin is used, a pull-up resistor, e.g. 10 kΩ, must be connected.

Inverter system efficiency

Efficiency is defined as the ratio of output power to input power (Power out)/(Power in). This is a very important parameter when working with portable energysources(batteries and accumulators), where the time of operation on one charging cycle counts. The efficiency of this pulse system is about 85 % - 95 %.
