The Boost 3 Click Board™ is a compact add-on board that contains a boost converter with an integrated current mirror function. This board features the TPS61391, a 700-kHz pulse-width modulating (PWM) Step-Up converter with a 70V switch FET with an input voltage up to 5.5V from Texas Instruments. The TPS61391 includes an accurate current mirror, with two selectable gain options (1:5 or 4:5), and provides high optical-power protection with an additional FET in series with the APD power path, with the typical response time of 0.5µs. This Click Board™ is designed to be used for applications such as biasing and monitoring the avalanche photodiodes (APD) in the optical receivers, but it also can be used as a high voltage sensor supply or in battery-powered and automotive applications.
The Boost 3 Click Board™ is supported by a mikroSDK compliant library, which includes functions that simplify software development. This Click Board™ comes as a fully tested product, ready to be used on a system equipped with the mikroBUS™ socket.
Software Support
We provide a library for the Boost 3 Click Board™ on our LibStock page, as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.
Library Description
The library covers the necessary function that enables the usage of the Boost 3 Click Board™. User can enable or disable the device.
Key Functions
void boost3_dev_enable ( uint8_t state );- Function is used to enable or disable the device.
Example Description
The application is composed of three sections :
- System Initialization - Initializes GPIO and LOG structures, and set CS pin as output.
- Application Initialization - Start to write log and gives instructions to the user.
- Application Task - Demonstrates use of Boost 3 click board by by reading user's command input from USART terminal and turning the device on or off accordingly. User can use the on-board potentiometer to adjust 'Vout' voltage.
void application_task ( )
{
char cmd;
if ( UART_Rdy_Ptr() )
{
cmd = UART_Rd_Ptr( );
cmd -= 48;
boost3_dev_enable( cmd );
if( cmd == BOOST3_ENABLE )
{
mikrobus_logWrite( "The device is turned on!", _LOG_LINE );
mikrobus_logWrite( "Use on-board potentiometer", _LOG_LINE );
mikrobus_logWrite( " to adjust 'Vout' voltage", _LOG_LINE );
}
else
{
mikrobus_logWrite( "The device is turned off!", _LOG_LINE );
}
}
}
The full application code, and ready to use projects can be found on our LibStock page.
Other mikroE Libraries used in the example:
- GPIO
- UART
Additional Notes and Information
Depending on the development board you are using, you may need a USB UART click, USB UART 2 click or RS232 click to connect to your PC, for development systems with no UART to USB interface available on the board. The terminal available in all MikroElektronika compilers, or any other terminal application of your choice, can be used to read the message.
MIKROSDK
The Boost 3 Click Board™ is supported with mikroSDK - MikroElektronika Software Development Kit. To ensure proper operation of mikroSDK compliant Click board™ demo applications, mikroSDK should be downloaded from the LibStock and installed for the compiler you are using.
