Product description: U1V11F5 - 5V 1,2A step-up converter - Polol 2562.

A controller that increases the voltage from 0.5 to 5.5 V to a fixed 5 V value. When 5 V is exceeded at the input, the system automatically switches to rope mode of the voltage reducing regulator. The efficiency of the inverter is 70 - 90 % depending on the specified input voltage. The system has a standby mode, which is switched on by giving a low state to the SHDN output. We also offer a version with an output voltage of 3.3 V.

Outputs

The module has three outputs:

  • SHDN - system shutdown - low state, which makes the system go into low power consumption state. The output is pulled to the VIN via a 100 kΩ resistor, which makes the system switched on by default. If the pin is not used, it can be left unconnected or connected to an adjacent VIN. Otherwise, follow the instructions below:
    • For VIN < 0.8 V, the voltage value at SHDN must be below 0.1 * VIN to lock the controller and above 0.9 * VIN to unlock it.
    • For 0.8 V ≤ VIN ≤ 1.5 V, the voltage value at SHDN must be below 0.2 * VIN to lock the controller and above 0.8 * VIN to unlock it.
    • For VIN >11.5 V , the voltage value at SHDN must be below 0.4 V to lock the controller and above 1.2 V to unlock it.

The connectors are properly signed on the board. Output Raster 2.54 mm - popular connectorsgoldpin, allow the module to be mounted incontact plateorconnectionby means ofcables.

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 energy sources (batteries and accumulators), where the time of operation on one charging cycle counts. The efficiency of this pulse system is about 70 % - 90 %. The output current depends on the input voltage, details on the diagram:

Efficiency and output current of the system at 5 V output voltage.

Dangerous voltage pulses

When connecting the power supply to the module, dangerous, short, high amplitude eclectic impulses (so-called pins) may appear, which may permanently damage the system. According to Polol's tests, for input voltages above 4.5 V, the pins may have an amplitude high enough to damage the module. In order to protect against this unwanted phenomenon it is recommended to solder a capacitor of at least 33 uF as close as possible to the pins powering the converter.
