RF6280 Power Management IC

The RF6280 is a multi-functional Power Management Unit which is used in conjunction with power amplifiers and designed to be used in 3V handheld systems. The RF6280 consists of a DC-DC converter three 2.85V LDOs and a bias control circuit to adjust the PA bias. The DC-DC Converter is a buck converter that provides high efficiency over a wide output voltage range with minimal ripple. It has a fast response to load and line transients and fast response to program (VSET) voltage changes. The converter includes an auto-bypass function which allows the handset to operate at lower battery voltage while helping maintain PA linearity at maximum output power. The converter output voltage is set by a variable control voltage VSET. The RF6280 has three individual LDOs which are enabled by a digital two bit logic signal. The three LDO outputs are used for band select in tri-band WCDMA handsets.
