Description The SKY87020-11 is a high-efficiency RF front-end power management IC for APT RF power amplifier (PA) applications in portable battery powered devices. This IC includes a high-efficiency DC-DC voltage converter with a 4.5 V reference supply to provide a user-programmable RF PA APT supply for a 2.5 V to 5.5 V input range. The SKY87020-11 also provides an additional 4.5 V bias supply for RF PA operation. This bias voltage output can supply load currents up to 3 mA and is available whenever the device is enabled. When the device is disabled, the VIN supply is bypassed to the 4V5 output. The SKY87020-11 is available in a 16-pin, 2.005 mm  2.005 mm Chip Scale Package (CSP) package. A typical application circuit is shown in Figure 1.
