The typical LTC4223 application is in a Carrier board
for Advanced Mezzanine Cards (AMC), delivering 3.3V
auxiliary and 12V power to the AMC module. A control-
ler on the Carrier board sequences the turn-on of power
supplies and manages the fault and power-good reports
from the LTC4223.
The LTC4223 detects board presence during insertion and
extraction, allowing power to be delivered in a controlled
manner without damaging the connector. The typical
LTC4223 application circuit is shown in Figure 1. External
component selection is discussed in detail in the Design
Example section.
APPLICATIONS INFORMATION
Turn-On Sequence
The power supplies delivered to an AMC module are
controlled by the external N-channel pass transistor, Q1 in
the 12V power path and an internal pass transistor in the
3.3V auxiliary power path. Sense resistor R
S
monitors the
12V load current for fault detection and current sensing
information. GATE capacitor C
G
provides gate slew rate
control to limit the inrush current. Resistor R
G
with C
G
compensates the current control loop while R3 prevents
parasitic oscillations in Q1.
