ADP1613-12-EVALZ: 12V @ 2A, 2.5 ~ 5.5V in, Boost

Summary

The ADP1612/ADP1613 evaluation module 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 (ADP1612) and 12 V (ADP1613) output voltages. The evaluation boards can be adjusted for different output voltages by changing R1 and R2. In addition, L1, D1, C3, and R3 may need to be adjusted and should be recalculated to ensure stable operation.

The ADP1612/ADP1613 evaluation module operates in pulse-width modulation (PWM) current mode with up to 94% efficiency. The shunt-selectable switching frequency and PWM current-mode architecture allow for excellent transient response, easy noise filtering, and the use of small, cost-saving external inductors and capacitors. Other key features include a 33 nF soft start capacitor, undervoltage lockout (UVLO), thermal shutdown (TSD), and jumper selected enable. The evaluation module demonstrates the operation and performance of the ADP1612/ADP1613.

This data sheet includes I/O descriptions, setup instructions, the schematic, and the PCB layout drawings for the ADP1612/ ADP1613 step-up converter evaluation module. Use this data sheet in conjunction with the ADP1612/ADP1613 data sheet.
