The FAN5362 is a 500mA or 750mA, step-down, switching voltage regulator that delivers a fixed output voltage from an input voltage supply of 2.7V to 5.5V. Using a proprietary architecture with synchronous rectification, the FAN5362 is capable of delivering a peak efficiency of 96%, while maintaining efficiency over 90% with load currents as low as 1mA. This regulator transitions seamlessly into and out of 100% duty cycle operation when the supply dips to or below the regulation setpoint and smoothly recovers full regulation without overshoot when the supply recovers. The regulator operates at a nominal fixed frequency of 3MHz, which reduces the value of the external components to 1µH for the output inductor and 4.7µF for the output capacitor. The PWM modulator can be synchronized to an external frequency source. At moderate and light loads, pulse frequency modulation is used to operate the device in power-save mode with a typical quiescent current of 45µA. 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, operating at 3MHz. In shutdown mode, the supply current drops below 1µA, reducing power consumption. For applications that require minimum ripple or fixed frequency, PFM mode can be disabled using the MODE pin. The FAN5362 is available in 6-bump, 0.4mm pitch, Wafer-Level Chip-Scale Package (WLCSP) and 6-Lead 2 x 2mm Ultrathin Molded Leadless Package (UMLP).
