Product Details

The ADP1614 evaluation board is a complete step-up, dc-to-dc switching converter application with components selected to allow operation over the full range of input and load conditions for the 5 V (ADP1614-650-EVALZ) and 15 V (ADP1614-1.3-EVALZ) output voltages. The boost switching frequency is fixed to either 650 kHz (ADP1614-650-EVALZ) or 1.3 MHz (ADP1614-1.3- EVALZ). The evaluation boards can be adjusted for different output voltages by changing the feedback resistors, R1 and R2. To ensure stable operation, external components L1, R_CL, C_OUT, R_COMP, and C_COMP may also need to be recalculated and adjusted when the output voltage is changed.

The ADP1614 evaluation board operates in current mode, pulsewidth modulation (PWM) with up to 94% efficiency. The current mode PWM architecture allows for excellent transient response, easy noise filtering, and the use of small, cost-saving external inductors and capacitors. Other key features include a 47 nF soft start capacitor, undervoltage lockout (UVLO), thermal shutdown (TSD), and jumper selected enable. The evaluation board demonstrates the operation and performance of the ADP1614.

This user guide includes I/O descriptions, setup instructions, the schematic, and the PCB layout drawings for the ADP1614 step-up converter evaluation board.

Complete specifications for the ADP1614 are available in the ADP1614 data sheet and should be consulted in conjunction with this document when using the evaluation board.
