Product Details

Demonstration circuit 1212A-A is a monolithic step-down DC/DC switching regulatro featuring the LT3480 in the 3 × 3 DFN-10 package. The demo board provides 5V at 2A from a 6.3V to 38V input and has transient protection up to 60V. The demo boards default switching frequency is 800kHz, but the LT3480 has a SYNC pin which allows frequency synchronization to an external clock over a 250kHz to 2MHz range. The LT3480's quiescent current is 70uA, while the LT3685 has a 0.9mA quiescent current. 

An EMC filter at the input makes the circuit compatible with EMC standard EN55022 Class B.
