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.

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
