The Boost 3 Click Board™ is based on the TPS61391, a 700-kHz pulse-width modulating (PWM) Step-Up converter with a 70V switch FET with an input voltage up to 5.5 V from Texas Instruments. It supports an input voltage up to 5.5V and operates at a 700 kHz pulse-width modulation (PWM) crossing the whole load range. There are two ratio options for the current proportional to the APD current: MON1 (4:5) and MON2 (1:5). By connecting an additional RC filter for low ripple applications from the mirror output pins to the GND, the current flowing through the APD is converted into the voltage crossing the resistor from MON1/MON2 pins to GND. Additionally, a high power optical protection, with the response time typically of 0.5 μs, is integrated by clamping the pre-set current limit (program by the R6 resistor) and could recover automatically when the high optical power is removed.
The output voltage of the TPS61391 is externally adjustable using a resistor divider network. The relationship between the output voltage and the resistor divider is given by the equation:
VOUT = ( VREF + 0.1V ) * ( 1 + ( VR1 + R8 ) / R9 ) [V]
where VREF has a typical value of 1.2V. When the potentiometer has a 0V value, the output voltage has its minimum value of 20V. Increasing the resistance of a potentiometer and reaching its maximum value of 500kΩ, the output voltage also reaches its maximum value of 70V. The potentiometer featured on the Boost 3 Click Board™ can change the feedback thus influencing a change in the output voltage. This makes the Click board™ extremely practical because you can, with a simple turn of the potentiometer, get the wide voltage range.
The Boost 3 Click Board™ communicates with MCU using only one GPIO pin routed on the CS pin of the mikroBUS™ socket labeled as EN. An under-voltage lockout (UVLO) circuit stops the operation of the converter when the input voltage drops below the typical UVLO threshold of 2.5 V. When the input voltage is above the maximal UVLO rising threshold of 2.5 V, and the EN pin is pulled above the high threshold (1.2V minimum), the TPS61391 is enabled. When the EN pin is pulled below the low threshold (0.4 maximum), the device goes into Shutdown Mode.
It also possesses the output terminal labeled as APD used for biasing and monitoring the avalanche photodiodes (APD) and high optical power protection. There is an additional FET in series of power path connecting with the APD output terminal. When the current flowing through the external APD exceeds the short protection threshold, set by connecting the resistor from R6 to the ground, the on-resistance of the internal FET becomes larger to clamp the current within the protection threshold by lowering the APD bias voltage. It takes typically 0.5μs for the FET to respond in case of high optical power occurring. When the high optical power condition releases, the TPS61391 recovers automatically back to the Normal Operation Mode.
The Boost 3 Click Board™ is designed to be operated with both 3.3V and 5V logic voltage levels that can be selected via VCC SEL jumper. This allows for both 3.3V and 5V capable MCUs to use the GPIO communication line properly. However, the Click board™ comes equipped with a library that contains easy to use functions and an example code that can be used as a reference for further development.

The Boost 4 Click Board™ carries the TPS61230A, a high efficiency fully integrated synchronous boost converter from Texas Instruments. The Click is designed to run on a 3.3V power supply. Boost 4 Click drives the target chip through the digi pot, which has SPI communication with the microcontroller on the system.
Boost 4 Click is the power management solution for your next project.
Boost 4 Click provides an adjustable output voltage through the SPI DAC, that drives the FB pin to set desired voltage. The Click is capable of delivering up to 2.4-A output current at a 5V output with the 2.5-V input supply.
The TPS61230A device is a high efficiency fully integrated synchronous boost converter. It integrates 6-A, 21-mΩ and 18-mΩ power switches.
During the light load condition, the TPS61230A automatically enters into the PFM operation for maximizing the efficiency with the lowest quiescent current. In the shutdown by pulling EN pin to the logic low, the load is completely disconnected from the input, and the input current consumption is reduced to below 1.0 A.
