Fairchild's FAN53601/11 is a 6MHz, step-down switching voltage regulator, available in 600mA or 1A options, that delivers a fixed output from an input voltage supply of 2.3V to 5.5V. Using a proprietary architecture with synchronous rectification, the FAN53601/11 is capable of delivering a peak efficiency of 92%, while maintaining efficiency over 80% at load currents as low as 1mA. The regulator operates at a nominal fixed frequency of 6MHz, which reduces the value of the external components to as low as 470 nH for the output inductor and 4.7µF for the output capacitor. In addition, the Pulse Width Modulation (PWM) modulator can be synchronized to an external frequency source. At moderate and light loads, Pulse Frequency Modulation (PFM) is used to operate the device in Power-Save Mode with a typical quiescent current of 24µA. 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 6MHz. 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.
Fairchild's FAN53555 Digitally Programmable TinyBuck® Regulators are a step-down switching voltage regulator that delivers a digitally programmable output from an input voltage supply of 2.5V to 5.5V. The output voltage is programmed through an I2C interface capable of operating up to 3.4MHz. Using a proprietary architecture with synchronous rectification, the FAN53555 is capable of delivering 5A continuous at over 80% efficiency, while maintaining over 80% efficiency at load currents as low as 10mA. Pulse currents as high as 6.5A can be supported by the 05 option. The regulator operates at a nominal fixed frequency of 2.4MHz, which reduces the value of the external components to 330nH for the output induction and as low as 20µF for the output capacitor. Additional output capacitance can be added to improve regulation during load transients without affecting stability. Inductance of up to 1.2µH may be used with additional output capacitance.
Fairchild's FAN501/FAN501A Offline DCM/CCM Flyback PWM Controllers that are an advanced PWM controller that simplifies isolated power supply design that requires CC regulation of the output.
