– IR3092 Block Diagram
PWM Operation
The IR3092 is a fully integrated 2 phase interleaved PWM control IC which uses voltage mode control with trailing edge
modulation. A high-gain wide-bandwidth voltage type Error Amplifier in the control IC is used for the voltage control loop.
The PWM block diagram of the IR3092 is shown in Figure 2.
Refer to Figure 3. Upon receiving a clock pulse, the RSFF is set, the internal PWM ramp voltage begins to increase, the
low side driver is turned off, and the high side driver is then turned on. For phase 1, an internal 10pf capacitor is charged
by a current source that
’s proportional to the switching frequency resulting in a ramp rate of 57mV per percent duty cycle.
For example, if the steady-state operating switch node duty cycle is 10%, then the internal ramp amplitude is typically
570mV from the starting point (or floor) to the crossing of the EAOUT control voltage. When the PWM ramp voltage
exceeds the Error Amplifier’s output voltage, the RSFF is reset. This turns off the high side driver, turns on the low side
driver, and discharges the PWM ramp to 0.7V until the next clock pulse.
