General Desc ription
The MAX8500–MAX8504 PWM DC-to-DC buck converters
are optimized with integrated bypass FET (0.25
typ)
to provide power to the PA in N-CDMA and W-CDMA
cell phones. The devices have a low on-resistance FET
to bypass the external inductor for low dropout of only
150mV at 600mA load, regardless of inductor series
resistance. The supply voltage range is from 2.6V to
5.5V and the guaranteed converter output current is
600mA. The 1MHz PWM switching frequency allows for
small external components.
The MAX8500–MAX8503 are dynamically controlled to
provide varying output voltages from 0.4V to V
BATT
.
The LDO regulation point is slightly lower than the PWM
converter such that the transition into and out of dropout
is smooth, regardless of the inductor resistance. The
MAX8504 is programmed for fixed 1.25V to 2.5V output
with external resistors. It features a high-power bypass
mode that connects the output directly to the battery. All
devices are designed to achieve an output settling time
of less than 30μs for a full-scale change in output volt-
age and load current.
The MAX8500–MAX8504 are available in a 12-lead
4mm x 4mm thin QFN package (0.8mm max height).
