DC1570A-B

DC1570A-B demonstration circuit is a 1.0MHz current mode step-down switching regulator with programmable output current limit. The current limit accurately controls the system power dissipation and reduces the size of the power path components. The demo board operates with a 7.5V to 36V (60 transients) input voltage range and provides a 3.3V output. The current limit can be set to 0.6A, 0.AV, 1A or 1.2A using jumpers J2 and J3. The LT3663-5.0 includes a low current shutdown mode, input overvoltage lockout and thermal shutdown. The LT3663EDCB-5.0 is available in an 8 lead (2mm × 3mm) DFN surface mount package with exposed pad.

• Current limit range from 0.6 to 1.2A(selectable ±20% )
