... NOTE Connected to GND open or connected to 3.3V SS through pull-up resistors. 8 IPM6210A Mode-Compensated Droop An output voltage ‘droop’ active voltage positioning is NOMINAL now widely used in the computer power applications. The OUT1 VID0 VOLTAGE technique is based on raising the converter voltage at light load in anticipation of the possible load current step ...

... CPU 2 Ch1 50mV Ch2 5.0A FIGURE 4. The IPM6210A incorporates a new proprietary droop technique specially designed for the SpeedStep converters and provides mode-compensated, relatively equal droop in both, the performance and the battery- optimized modes. The droop is set as a fraction of the VID programmed voltage and the gain in the current loop is different for each VID combination ...

... Both PWM controllers use the lower MOSFET’s on-resistance - r to monitor the current for protection DS(ON) against shorted outputs. The sensed voltage drop after amplification is compared with an internally set threshold. 11 IPM6210A Several scenarios of the current protection circuit behavior are possible ...

... The minimum practical output inductor value is the one that keeps inductor current just on the boundary of continuous conduction at some minimum load. The industry standard practice is to choose the minimum current somewhere from 10% to 25% of the nominal current. At light load, IPM6210A is PWM controllers automatically switch to a hysteretic mode either operation to sustain high efficiency ...
