... Deeper Sleep to Active mode, holding DPRSLPVR LOW will result in maximum dV/dt. Therefore, the ISL6262 is IMVP-6 compliant for DPRSTP# and DPRSLPVR logic. Intersil result, high-speed input voltage steps do not result in significant output voltage perturbations. In response to load current step increases, the ISL6262 will transiently raise the switching frequency so that response time is decreased and current is shared by two channels ...

When temperature increases, the NTC resistor value on NTC pin decreases. Thus, the voltage on NTC pin decreases to a level lower than 1.18V. The comparator output changes polarity and turns SW1 off and connects SW2 to 1.20V. This pulls ...

... Do not let the mismatch get larger than 600Ω. To reduce the mismatch, multiply both Rdrp1 and Rdrp2 by the appropriate factor. The appropriate factor in the example is (EQ. 22) 1392/853 = 1.632. In summary, the predicted load line with the designed droop network parameters based on the Intersil design tool is shown in Figure 35. 84mV ( ) Rdrp1 --------------- - Rdrp1 Rdrp2 ...
