产品详情

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, RCL, COUT, RCOMP, and CCOMP 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.
