2 MHz 650 mA Step Down Converter for RF Power Amplifiers in
Tiny 8-pin WCSP Package
High-Efficiency Step-Down Converter
Output Current up to 650 mA
The
TPS6270x
device
is
a
high-efficiency
synchronous step-down DC-DC converter optimized
V
IN Range From 2.5 to 6.0 V
for RF power-amplifier (PA) applications. It provides
2.0-MHz Fixed-Frequency Operation
up to 650 mA of output current from a single Li-Ion
Clock Dithering (TPS62701)
cell.
Dynamic Voltage Control With External
The device converts input voltages from 2.5 to 6.0 V
Reference (1.3 V to 3.09 V)
down to an output voltage set by an external analog
reference voltage applied to the pin VCON. The
Fast Output-Voltage Settling (1.3 V to 3.09 V in
output voltage follows the external reference by an
20
s)
internal gain of 2.5 within the limits of 1.3 V to 3.09 V.
Soft Start
This scheme adjusts the output voltage of the DC/DC
Overload Protection
converter and therefore the output power of an
RF-PA.
Undervoltage Lockout
Thermal Protection
The TPS6270x operates in fixed-frequency PWM
mode at a 2.0-MHz switching frequency to minimize
8-Pin WCSP Package
RF interference. This converter operates with only
three small external components; an input capacitor,
inductor and output capacitor. The TPS62701 has in
Cell Phones, Smart Phones
addition a built-in clock-dithering circuit to reduce RF
Battery-Powered RF Amplifier
noise.
The TPS6270x is available in a tiny 8 pin lead free
WCSP package for smallest solution size.
