Quad Channel Monolithic Power Stage

DESCRIPTION

The SiP2204 is a quad channel, fully-integrated monolithic

power stage optimized for multi-phase synchronous buck

applications. The part has very fast propagation to enable

switching frequencies of up to 10 MHz/channel and offers a

high power density design for use in applications such as

envelope tracking power supplies for RF power amplifiers

used in next generation 4G base stations.

Packaged in QFN32 5 x 5, SiP2204 supports input voltages

up to 24 V and delivers 500 mA continuous current for each

channel.

The SiP2204 incorporates four independent MOSFET gate

driver ICs that work with both 3.3 V and 5 V PWM inputs.

FEATURES

• QFN32 5 x 5 package

• Power stage input up to 24 V

• 500 mA per channel continuous current

• 2 A per channel peak current capability

• High frequency operation beyond 5 MHz

• 3.3 V and 5 V PWM logic

• Low PWM propagation delay (typical 13 ns)

• Enable feature to put the output at high impedance when

disabled

• Junction temperature: -40 °C to +125 °C

APPLICATIONS

• Envelope tracking (ET) supplies for RF power amplifiers

(LDMOS, GaAs FET, GaAs HBT or GaN based)

• Synchronous buck converters
