Overview

MAX5025–MAX5028 19-2239; Rev 2; 3/09 EVAALVUAAILTAIOBNLEKIT 500kHz, 36V Output, SOT23, PWM Step-Up DC-DC Converters General Description The MAX5025–MAX5028 constant-frequency, pulsewidth modulating (PWM), low-noise boost converters are intended for low-voltage systems that often need a locally 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 at 500kHz.
The constant-frequency, current-mode PWM architecture provides for low output noise that is easy to filter.
A 40V lateral DMOS device is used as the i...
