High-Efficiency, Low-IQ, PMICs with Dynamic Voltage Management for Mobile Applications (i.e., 1.8V to 2.5V) ramp-rate control. During a positive voltage change, the output-voltage dV/dt is as fast as possible. To avoid this fast output dV/dt, disable REG6 or REG7 before changing the output. With this method, the soft-start ramp rate limits the output dV/dt, and therefore, the input current is controlled. During a negative voltage change (i.e., 2.5V to 1.

UVLO forces the device to a dormant state. In UVLO, the input current is very low (1.5µA) and all regulators are off.
High-Efficiency, Low-IQ, PMICs with Dynamic Voltage Management for Mobile Applications For example, to set VLBOR to 3.6V and VLBOF to 3.2V, choose R3 to be 1MΩ. Then, R1 = 1.8MΩ and R2 = 80kΩ. If the low-battery-detector feature is not required, connect LBO to ground and connect LBF and LBR to IN. Internal Off-Discharge Resistors Each regulator on the MAX8660/MAX8661 has an internal resistor that discharges the output capacitor when the regulator is off (Table 8).

High-Efficiency, Low-IQ, PMICs with Dynamic Voltage Management for Mobile Applications Input Capacitor Selection The input capacitor in a step-down DC-DC converter reduces current peaks drawn from the battery or other input power source and reduces switching noise in the controller. The impedance of the input capacitor at the switching frequency should be less than that of the input source so that high-frequency switching currents do not pass through the input source.
