It provides a fixed output voltage level ranging from 1.0V to 1.8V. Other voltage options are available on request. The FAN4603 converter is offered as an ultra-miniature “Solder and Play” solution that requires no external components and is able to achieve a DC accuracy of ±2% PWM and an output ripple less than 12mV. Total footprint is 4.0 x 2.5mm with a maximum height of 1.1mm. It can be used in small battery-powered devices and applications with distributed DC POL requirements. At moderate and light loads, pulse frequency modulation is used to operate the device in power-save mode with a typical quiescent current of 35µA. Even with such a low quiescent current, the part exhibits excellent transient response during large load swings. At higher loads, the system automatically switches to fixed-frequency control. In shutdown mode, the supply current drops below 2µA, reducing power consumption.
