GENERAL DESCRIPTION
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.

and R3 may need to be adjusted and should be recalculated to

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.
