1 / 18 page  Vishay Siliconix SiC413 Document Number: 69057 S09-2250-Rev. D, 26-Oct-09 www.vishay.com 1 microBUCKTM SiC413 4-A, 26-V Integrated Synchronous Buck Regulator DESCRIPTION The SiC413 is an integrated, dc-to-dc power conversion solution with built-in PWM-optimized high- and low-side N-channel MOSFETs and advanced PWM controller. The SiC413 provides a quick and easy to use POL voltage regulation solution for a wide range of applications. Vishay Siliconix’s Proprietary packaging technology is used to optimize the power stage and minimize power losses associated with parasitic impedances and switching delays. The co-packaged Gen III TrenchFET power MOSFET devices deliver higher efficiency than lateral DMOS monolithic solutions. FEATURES • Integrated PWM controller and Gen III trench MOSFETs • Quick and easy single chip converter • Integrated current sense • Cycle by cycle over-current protection • Built-In bootstrap diode • Output over-voltage protection • Under voltage lockout • Thermal shutdown • Soft start • Break-before-make operation • Halogen-free according to IEC 61249-2-21 definition • Compliant to RoHS directive 2002/95/EC APPLICATIONS • LCD TV, set top box and DVD player • Desktop PC and server • Add-in graphics board • Memory, FPGA or µP device power supplies • Point of load dc-to-dc conversion • Telecom and networking equipment TYPICAL APPLICATION PRODUCT SUMMARY Input Voltage Range 4.75 V to 26 V Output Voltage Range 0.6 V to 13.2 V Operating Frequency 500 kHz Continuous Output Current 4 A Peak Efficiency 93 % Highside/Lowside RDS_ON 35 m Ω/19 mΩ Package SO-8 Figure 1 - Typical Application Circuit Enable VIN VO Controller BOOT VSW FB COMP EN 1 2 3 4 5 6 7 8 SiC413 |
