MAX5026EUT+T

The MAX5026EUT+T is a 500KHz, 36V output, PWM step up DC to DC converter in 6 pin SOT-23 package. It is a constant-frequency, pulse width modulating (PWM), low-noise boost converter are intended for low-voltage systems that often need a locally generated high voltage. This device is capable of generating low noise, high output voltages required for varactor diode biasing in TV tuners, set-top boxes and PCI cable modems. It operates 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 internal power switch, making the device ideal for boost converters up to 36V. It requires the use of external feedback resistors to set the output voltage.
