Description
The 12A Digital Pico DLynx
TM
power modules are non-isolated dc-dc converters that can deliver up to 12A of output
current. These modules operate over a wide range of input voltage (V
IN
= 3Vdc-14.4Vdc) and provide a precisely
regulated output voltage from 0.6Vdc to 5.5Vdc, programmable via an external resistor. Features include a digital
interface using the PMBus protocol, remote On/Off, adjustable output voltage, over current and overtemperature
protection. The PMBus interface supports a range of commands to both control and monitor the module. The
module also includes the Tunable Loop
TM
feature that allows the user to optimize the dynamic response of the
converter to match the load with reduced amount of output capacitance leading to savings on cost and PWB area.
