Compact 5V, 10A Synchronous Silent Switcher 2 Buck Regulator Reduces Heat EMI & Footprint

 Analog Devices  announces the Power by Linear™ LTC3310S, a 5V, 10A low EMI monolithic synchronous buck converter. The device’s fixed frequency peak current mode architecture is ideal for high step-down ratio applications that demand fast transient response. The LTC3310S uses the Silent Switcher®2 architecture with integrated hot loop bypass capacitors to deliver a highly efficient, small footprint solution at frequencies up to 5MHz with excellent EMI performance. Multiphase operation enables direct paralleling of multiple devices for higher current. The LTC3310S’ 2.25V to 5.5V input range supports a wide variety of applications, including most intermediate bus voltages. Integrated low on-resistance MOSFETs deliver continuous load currents as high as 10A with minimal thermal derating. Output voltages ranging from 0.5V to VIN are ideal for point-of-load applications such as high current/low voltage DSP/FPGA/GPU/ASIC reference designs. Other key applications include optical networking, telecom/datacom and automotive systems, distributed power architectures and general medium to high power density systems.

The LTC3310S’ low 35ns minimum on-time enables a high step-down ratio power supply at high frequency. 100% duty cycle operation delivers low dropout performance. The operating frequency can be synchronized to an external clock. The LTC3310S total reference voltage accuracy is ±1% over the –40°C to 125°C operating junction temperature range. Additional features include a power good signal when the output is in regulation, precision enable threshold, output overvoltage protection, thermal shutdown, die temperature monitor, clock synchronization, mode selection and output short-circuit protection. The LTC3310S is available in a thermally enhanced

18-lead 3mm × 3mm × 0.94mm LQFN package. The E- and I- grades are specified from

–40°C to 125°C operating junction temperature range. All versions are available from stock. For more information, visit http://www.analog.com/LTC3310S
