... O 10mV/DIV FIGURE 15. OUTPUT RIPPLE 1.8V Applications Information The ISL98012 is a fixed frequency step-up pulse-width modulation (PWM) regulator. The input voltage range is 1.8V to 13.2V and output voltage range is 4.5V to 17V. The switching frequency (up to 750kHz) is decided by the resistor connected to RT pin. Start-Up During start-up reaches a threshold of about 1 ...

... Theoretically, the input capacitor has a ripple current of ΔI Due to high-frequency noise in the circuit, the input current ripple may exceed the theoretical value. A larger capacitor will reduce the ripple further. 8 ISL98012 The inductor has peak and average current decided by Equations 4 and ...
