Positive buck regulator Li'lBoard page.
Model number: LB2.06.
Description: Using TI's TPS5410, 1A buck regulator chip, this L'ilboard provides an efficient means of converting a higher voltage to a lower one.
Applications: Convert a voltage within the 5.5...36 V range to a lower one without the wasted power of a linear regulator. Can produce an output as low as 1.22 V. The normal set-up is to produce 1.5 V. This is increased by paralleling a through-hole (1/8 W size) resistor with R2.
Features:
•Easy set up of desired voltage by paralleling an on-board resistor.
