XC6377 series Step-Down DC/DC Converter The XC6376/77 series are step-down DC/DC converters with built-in P-Channel power MOSFETs. A highly efficient DC/DC converter with output currents of 500mA can be realised using only four peripherals - a coil, a diode and 2 capacitors. Output voltage can be internally set-up in 0.1V increments (±2.5%) between 1.5V and 6.0V (VOUT type). Alternatively, output voltage can be set-up at will using a 1.0V internal reference voltage source and peripherals (FB type). It is possible to reduce the size of the peripherals used since the switching frequency is 300kHz. The PWM/PFM switchable XC6377 operates in PFM mode during light loads and is highly efficient from light loads to large output currents. The required soft start time can be set-up using an the external capacitor and the stand-by function reduces supply current to less than 2.5uA. U.V.L.O and protection are also built-in. Features:
