RF6650 is a pulse-width modulated (PWM),
voltage-mode controlled DC-DC converter unit
designed to supply power to W-CDMA power amplifiers.
The output voltage is continuously programmable
through the VSET analog input pin. The converter
has been optimized for high efficiency at light
current load conditions, fast transient response
times to meet W-CDMA 25 µs slot-to-slot transition
specifications, and low noise by maintaining
a constant switching frequency, while supplying
up to 650 mA in PWM-controlled or bypass modes.
Efficiency > 95 %
Transient Response < 25 ms
650 mA Load Current Capability
Constant Switching Frequency
