The Si9160 Controller for RF Power Amplifier Boost Con-
verter is a fixed-frequency, pulse-width-modulated power
conversion controller designed for use with the Si6801 appli-
cation specific MOSFET. The Si9160 and the Si6801 are
optimized for high efficiency switched-mode power conver-
sion at 1 MHz and over. The device has an enable pin which
can be used to put the converter in a low-current mode com-
patible with the standby mode of most cellular phones. A
wide bandwidth feedback amplifier minimizes transient
response time allowing the device to meet the instantaneous
current demands of today’s digital protocols. The input volt-
age range accommodates minimal size and cost battery
pack configurations.
Optimizing the controller and the synchronous FETs results
in the highest conversion efficiency over a wide load range at
the switching frequencies of interest (1 MHz or greater). It
also minimizes the overshoot and gate ringing associated
with drive current and gate charge mismatches.
When disabled, the converter requires less than 330 μA. This
capability minimizes the impact of the converter on battery
life when the phone is in the standby mode.
Finally, operating voltage is optimized for LiIon battery oper-
ation (2.7 V to 4.5 V) and can also be used with three-cell
NiCd or NiMH (3 V to 3.6 V), as well as four-cell NiCd or
NiMH (4 V to 4.8 V) battery packs.
Frequency control in switching is important to noise manage-
ment techniques in RF communications. The Si9160 is easily
synchronized for high efficiency power conversion at fre-
quencies in excess of 1 MHz.
APPLICATION CIRCUIT
The Si9160 is available in both standard and lead (Pb)-free
packages.
