Deﬁnition of Green^TM, document number

SQ04–0074.

The SKY87020-13 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 SKY87020-13 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 4.5 V bias supply is

shut down.

The SKY87020-13 is available in a 16-pin, 2.005 mm 

2.005 mm Chip Scale Package (CSP).

A typical application circuit is shown in Figure 1.
