Si P2204 Vishay Siliconix Quad Channel Monolithic Power Stage DESCRIPTION The Si P2204 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, Si P2204 supports input voltages up to 24 V and delivers 500 m A continuous current for each channel. The Si P2204 incorporates four independent MOSFET gate driver ICs that work with both 3.3 V and 5 V PWM inputs. TYPICAL APPLICATION CIRCUIT Features - QFN32 5 x 5 package - Power stage input up to 24 V - 500 m A 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, Ga As FET, Ga As HBT or Ga N based) - Synchronous buck converters VDRV12 VCIN EN PWM1 AGND VIN12 VZ12 SW1 PGND Fig. 1 - Typical Application Circuit for Si P2204 (channel 1 shown) S20-0486-Rev.
