IR3529
share adjust amplifier of the phase will pull up the starting point of the PWM ramp thereby decreasing its duty cycle and
output current. The current share amplifier is internally compensated so that the crossover frequency of the current
share loop is much slower than that of the voltage loop and the two loops do not interact. For proper current sharing
the output of current sense amplifier should not exceed (VCCL-1.4V) under all operating condition.

Tri-State Gate Drivers
The gate drivers are design to provide a 2A source and sink peak current (Bottom gate driver can sink 4A). An
adaptive non-overlap circuit monitors the voltage on the GATEH and GATEL pins to prevent MOSFET shoot-
through current and minimizing body diode conduction. The non-overlap latch is added to eliminate erroneous
triggering caused by the switching noise. A fault condition is communicated to the phase IC via the control IC’s
error amplifier without an additional dedicated signal line. The error amplifier’s output is driven low in response to
any fault condition detected by the controller, such as VCCL under voltage or output overload, disabling the phase
TM TM
drives the bottom gate output low. This tri-state operation prevents negative inductor current and negative output
voltage during power-down.
