Reduction of heat, EMI, and footprint for high power density applications
Supports multi-phase operation, parallel connection of multiple devices
Analog Devices announced on the 6th that it is releasing a new monolithic synchronous buck converter, the Power by Linear LTC3310S, featuring 5V, 10A, and low EMI.

The new product is based on a fixed-frequency peak current mode architecture, making it ideal for high step-down ratio applications requiring fast transient response characteristics.

The LTC3310S uses the Silent Switcher2 architecture with integrated hot-loop bypass capacitors to provide the best EMI performance and a high-efficiency, small-footprint solution at switching frequencies up to 5 MHz.

Since it supports multi-phase operation, multiple devices can be connected in parallel when a higher output current is required.

The input voltage range of the LTC3310S is 2.25V to 5.5V, supporting a wide range of applications including most intermediate bus voltages.

It integrates a low on-resistance MOSFET, minimizing thermal performance limitations while reaching a 10A level It can provide high continuous load current.

The output voltage range is from 0.5V to VIN, making it ideal for point-of-load (POL) applications such as high-current/low-voltage DSP/FPGA/GPU/ASIC reference designs.

In addition to this, it supports various key applications such as optical networking, telecom/datacom and automotive systems, distributed power architectures, and general medium to high power density systems.

The minimum on time of the LTC3310S is low at 35ns, supporting power supplies with a high step-down ratio at high frequencies.

100% duty cycle operation provides low dropout performance. The operating frequency can be synchronized with an external clock.

The total reference voltage accuracy of the LTC3310S is ±1% over an operating temperature range of –40°C to 125°C.

In addition, when the output is controlled, it also provides a power good signal, precision enable threshold, output overvoltage protection, shutdown in case of overheating, die temperature monitoring, clock synchronization, mode selection, and output short-circuit protection functions.

The LTC3310S is supplied in a thermally enhanced 18-pin 3mm x 3mm x 0.94mm LQFN package. The E- and I-grade products are designed to support an operating temperature range of –40°C to 125°C.
