1 / 43 page 1/43 XCM520 Series 600mA Synchronous Step-Down DC/DC Converter + Dual LDO Regulator ■GENERAL DESCRIPTION The XCM520 series is a multi chip module which comprises of a 600mA driver transistor built-in synchronous step–down DC/DC converter and a dual CMOS LDO regulator. The device is housed in small USP-12B01 package which is ideally suited for space conscious applications. The XCM520 can replace this dual DC/DC to eliminate one inductor and reduce output noise. The DC/DC converter with a built-in 0.42ΩP-channel MOS and a 0.52ΩN-channel MOS provides a high efficiency, stable power supply up to 600mA to using only a coil and two ceramic capacitors connected externally. The highly accurate, low noise, dual CMOS LDO regulator includes a reference voltage source, error amplifiers, driver transistors, current limiters and phase compensation circuits internally. The series is also fully compatible with low ESR ceramic capacitors. This high level of output stability is maintained even during frequent load fluctuations, due to the excellent transient response performance and high PSRR achieved across a broad range of frequencies. The EN function allows the output of each regulator to be turned off independently, resulting in greatly reduced power consumption. ■APPLICATIONS ●Mobile phones, Smart phones ●Bluetooth headsets ●WLAN PC cards ●Portable HDDs, SSDs ●PDAs, PNDs, UMPCs ●MP3 players, Media players ●Portable game consoles ●Cordless phones, Radio communication equipment ■FEATURES <DC/DC Convertor Block> Driver Transistor : 0.42Ω P-channel MOS Built-in Switching Transistor : 0.52Ω N-channel MOS Built-in Input Voltage Range : 2.7V ∼ 6.0V Output Voltage Range : 0.8V ∼ 4.0V High Efficiency : 92% (TYP.) * Output Current : 600mA Oscillation Frequency : 1.2MHz,3.0MHz (±15%) Soft-Start : Built-In Soft-Start Current Limiter Circuit : Constant Current & Latching Control : Fixed PWM, Auto PWM/PFM *Performance depends on external components and wiring on PCB wiring. <Dual LDO Regulator Block> Maximum Output Current : 150mA (Limiter 300mA TYP.)
