RFMD reveals new device for W-CDMA handsets
The converter has been optimised for high efficiency at light current load conditions.
The 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 analogue input pin. The converter has been optimised for high efficiency at light current load conditions, fast transient response times to meet W-CDMA 25µs slot-to-slot transition specifications, and low noise by maintaining a constant switching frequency, while supplying up to 650mA in PWM-controlled or bypass modes.

With over 95% efficiency and a transient response < 25ms, the module has a programmable output voltage.
The device, suitable for W-CDMA handsets, is currently available in production quantities. Pricing begins at $1.43 each for 25 pieces.
