DEMO CIRCUIT 1355

LTC4221

QUICK START GUIDE

LTC4221 Dual Hot Swap Controller/Power Se-

quencer w/ Dual Speed, Dual Level Fault Pro-

tection

DESCRIPTION

Demonstration circuit DC1355 is a dual hot swap

circuit featuring the LTC4221 Dual Hot Swap

Controller / Power Sequencer with Dual Speed,

Dual Level Fault Protection

DC1355 facilitates evaluation of the LTC4221

performance characteristics including supply

ramp-up transients, steady state operation, and

overcurrent fault conditions. On board LEDs in-

dicate input supply presence, output state, and

power good conditions.

The first LTC4221 channel controls a rail from

2.7V to 13.5V and the second one from 1V to

13.5V with condition that V

CC2

≤

CC1.

DC1355 is assembled to operate with a +12V rail

with 6A maximum current and a +3.3V rail with

3.0A maximum current.

Design files for this circuit board are avail-

able. Call the LTC factory.
