XC9515 Datasheet | Torex Semiconductor

DESCRIPTION The XC9515 series consists of 2 channel synchronous step-down DC/DC converters and a voltage detector with delay circuit built-in. The DC/DC converter block incorporates a P-channel 0.35Ω (TYP.) driver transistor and a synchronous N-channel 0.35Ω (TYP.) switching transistor. By minimizing ON resistance of the built-in transistors, the XC9515 series can deliver highly efficient and a stable output current up to 800m A. With high switching frequencies of 1MHz, a choice of small inductor is possible. The series has a built-in UVLO (under-voltage lock-out) function, therefore, the internal P-channel driver transistor is forced OFF when input voltage bees 1.8V or lower (for XC9515A, 2.7V or lower). The voltage detector block can be set delay time freely by connecting an external capacitor. W ith the manual reset function, the series can output a reset signal at any time. - APPLICATIONS - DVDs - Blue-ray Disk - LCD TVs, LCD modules - Multifunctional printers - Photo printers - Set top boxes - FEATURES DC/DC Input Voltage Range : 2.5V ~ 5.5V Output Voltage : VOUT1=1.2V ~ 4.0V VOUT2=1.2V~ 4.0V (Accuracy ±2%) Oscillation Frequency : 1MHz (Accuracy ±15%) High Efficiency : 95% (VIN=5V, VOUT=3.3V) Output Current : 800m A Control : PWM control Protection Circuits : Thermal Shutdown : Integral Latch (Over Current Limit) : Short Protection Circuit Ceramic Capacitor patible - TYPICAL APPLICATION CIRCUIT CIN1 PVSS 1 PVSS...
