Status:
Boost 7 Click is a compact add-on board that steps up the voltage from its input (supply) to its output (load). This board features the BD8316GWL, a dual DC/DC converter from Rohm Semiconductor. Each converter inside the BD8316GWL is designed with up to 200mA current limit generating well-regulated positive and negative outputs of ±3.3V or ±5V, making the BD8316GWL ideal for various applications. In addition to the possibility of working with both mikroBUS™ power rails, it also provides the opportunity of using an external power supply with a very low voltage of 2.5V. This Click board™ is used to step up an input voltage to some higher level, required by a load, for various applications that require "split rail" operating voltages.
Boost 7 Click 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.

Availability date:
Boost 7 Click is based on the BD8316GWL, a dual step-up and inverted DC/DC converter from Rohm Semiconductor that boosts an input voltage to a higher level required by an output load. The BD8316GWL switching regulator feature integrated N-channel FETs and power P-channel MOSFETs alongside a Soft Start feature. Each converter inside the LT1945 is designed with up to 200mA current limit generating well-regulated positive and negative outputs of ±3.3V or ±5V, making the BD8316GWL ideal for various portable applications.
As mentioned, the BD8316GWL can configure the positive and negative output voltage in the ±3.3V or ±5V range. The desired output voltage can be selected by positioning SMD jumpers labeled as V- SEL and V+ SEL to an appropriate position. It is also possible to control the activity of the output channels via two mikroBUS™ pins, SB1 and SB2 pins. These pins are routed to a default position of the AN and PWM pins of the mikroBUS™ socket. By setting these pins to a high logic state, we put the converter outputs to an active state, and regulated voltages are available at the output terminals. In the same way, setting these pins to a low logic level disables the channels.
This Click board™ can operate with either 3.3V or 5V logic voltage levels selected via the VCC SEL jumper. This way, both 3.3V and 5V capable MCUs can use the communication lines properly. Additionally, there is a possibility for the BD8316GWL power supply selection via jumper labeled as VIN SEL to supply the BD8316GWL from an external power supply terminal in the range from 2.5V to 5.5V or with a selected voltage from mikroBUS™ power rails. However, the Click board™ comes equipped with a library containing easy-to-use functions and an example code that can be used, as a reference, for further development.

We provide a library for the Boost 7 Click as well as a demo application (example), developed using Mikroe compilers. The demo can run on all the main Mikroe development boards.
Package can be downloaded/installed directly from NECTO Studio Package Manager (recommended), downloaded from our LibStock™ or found on Mikroe github account.
Library Description
This library contains API for Boost 7 Click driver.
Key functions
boost7_enable_out1
This function enables the OUT1 (V-) by setting the STB1 pin to high logic state.
boost7_disable_out1
This function disables the OUT1 (V-) by setting the STB1 pin to low logic state.
boost7_enable_out2
This function enables the OUT2 (V+) by setting the STB2 pin to high logic state.
Example Description
This example demonstrates the use of Boost 7 Click board™ by controlling the V- and V+ outputs state.
void application_task ( void )
{
log_printf( &logger, " OUT1 (V-) : ENABLEDrn" );
log_printf( &logger, " OUT2 (V+) : DISABLEDrnn" );
boost7_enable_out1 ( &boost7 );
boost7_disable_out2 ( &boost7 );
Delay_ms( 5000 );
log_printf( &logger, " OUT1 (V-) : DISABLEDrn" );
log_printf( &logger, " OUT2 (V+) : ENABLEDrnn" );
boost7_disable_out1 ( &boost7 );
boost7_enable_out2 ( &boost7 );
Delay_ms( 5000 );
}
The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager (recommended), downloaded from our LibStock™ or found on Mikroe github account.

Additional notes and informations
Depending on the development board you are using, you may need 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. A UART terminal is available in all Mikroe compilers.
This Click board™ is supported with mikroSDK - Mikroe 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.
