Stephanie Dai The LTC3865 is a high performance step-down controller with two constant frequency,
current mode, synchronous buck controllers and on-chip drivers. It offers high output
current capability over a wide input range. An important feature offered by the LTC3865 is its
highly accurate programmable output voltage. Internal precision feedback resistors make it
possible to select from nine different output voltages via two VID pins. The internal resistors
reduce the number of external components and assure 1% accuracy for low voltage rails.
The LTC3865 is suitable for applications
with input voltages up to 38V and output
voltages up to 5V. It can be synchronized
to a frequency of up to 750kHz and comes
in a compact 5mm Г— 5mm QFN package. The part is also capable of inductor DCR sensing, allowing for increased
efficiencies at higher load currents. These
features are ideal for wide input voltage
range, high current applications where
design solution footprint size is restricted. them floating can result in nine different output voltages from 0.6V to 5V (see
Table 1). Pin programming eliminates
at least four external feedback resistors, making the overall design solution
space conservative and cost effective. If
an application requires an output voltage not supported by pin programming,
one still has the option to use external …
