PWM Step-Down DC-DC Converters with 75m ?
Bypass FET for WCDMA and cdmaOne Handsets
General Description
The MAX8506/MAX8507/MAX8508 integrate a PWM step-
down DC-DC regulator and a 75m ? (typ) bypass FET to
power the PA in WCDMA and cdmaOne? cell phones.
The supply voltage range is from 2.6V to 5.5V, and the
guaranteed output current is 600mA. One megahertz
PWM switching allows for small external components.
The MAX8506 and MAX8507 are dynamically controlled
to provide varying output voltages from 0.4V to 3.4V. The
MAX8508 is externally programmed for fixed 0.75V to
3.4V output. Digital logic enables a high-power (HP)
bypass mode that connects the output directly to the bat-
tery for all versions. The MAX8506/MAX8507/MAX8508
are designed so the output settles in less than 30μs for a
full-scale change in output voltage and load current.
The MAX8506/MAX8507/MAX8508 are offered in 16-pin
4mm x 4mm thin QFN packages (0.8mm max height).
