General Description The MAX764 MAX765 MAX766 inverting switching regu lators are highly efficient over a wide range of load cur rents delivering up to 5W A unique current limited pulse frequency modulated PFM control scheme com bines the benefits of traditional PFM converters with the benefits of pulse width modulated PWM converters Like PWM converters the MAX764 MAX765 MAX766 are highly efficient at heavy loads Yet because they are PFM devices they use less than A of supply current vs 2mA to 10mA for a PWM device The input voltage range is 3V to 16V The output volt age is preset at 5V MAX764 12V MAX765 or 15V MAX766 it can also be adjusted from 1V to 16V using two external resistors Dual ModeTM The maxi mum operating VIN VOUT differential is 20V These devices use miniature external components their high switching frequencies up to 300kHz allow for less than 5mm diameter surface mount magnetics A stan dard H inductor is ideal for most applications so no magnetics design is necessary An internal power MOSFET makes the MAX764 MAX765 MAX766 ideal for minimum component count low and medium power applications For increased output drive capabil i ty or higher output voltages use the MAX774 MAX775 MAX776 or MAX1774 which drive an external power P channel MOSFET for loads up to 5W
