Availability date:
This is a voltage regulator based on D24V5Fx Step-Down buck converter. Such regulator can accept an input voltage up to 36V and efficienlty reduce it to 1.8 V with an output current of 500 mA.
The input voltage must be higher from 1V to make this regulator working proprely.
The regulator efficiency is in the range of 80% to 93%. Such is suited for low voltage application. It also feature a Power Safe mode that get activated at low load. The quiescent current is also very low when the shutdown is activated.
Those are great regulator for low power application powered from battery.
This buck regulator has 4 connections: VIN, GND (ground), VOUT (output voltage) and SHDN (shutdown).
The voltage regulator efficiency is defined as (Power out)/(Power in). It is an important measure of the performance, especially when battery life or heat are concerns.
The graph below whos the switching regulators efficiency. The efficiency of 80% to 93% for most combinations of input voltage, and load. A lower efficiency imply a high power dissipation (then dissipate more heat).
The maximum output current of the board depends of several factors:
The dropout voltage of a step-down regulator is the minimum amount by which the input voltage must exceed the regulator’s target output voltage in order to ensure the target output can be achieved.
Ex: if a 5 V regulator has a 1 V dropout voltage, the input must be at least 6 V to ensure the output is the full 5 V.
