1. Product introduction of the IC for Maxim SWITCHING REGULATOR
The IC for Maxim SWITCHING REGULATOR is a kind of Maxim pulse-width modulating (PWM), low-noise boost converters are intended for low-voltage systems that often need alocally generated high voltage. These devices are capable of generating low-noise, high output voltages required for varactor diode biasing in TV tuners, set-top boxes, and PCI cable modems. The MAX5025–MAX5028 operate from as low as 3V and switch at500kHz.
