Linear Technology Launched A New LTC7150S Device

Author:OMO Release Date: Jul 26, 2017

Linear Technology Corporation, a subsidiary of Analog Devices, Inc. (ADI), introduced the LTC7150S, a 20V, 20A monolithic synchronous buck converter with differential VOUT remote detection. The device's unique phase-lockable controlled turn-on time constant frequency current mode architecture reduces the burden of compensation and is well suited for high-voltage applications that require high-speed operation while requiring fast transient response. The LTC7150S utilizes Silent Switcher2 technology, including integrated channel capacitors to deliver cost-effective solutions with superior EMI performance while reducing layout constraints. Up to 12-phase multi-phase operation allows multiple devices to be directly connected in parallel to provide greater current with minimal input and output capacitance. VOUT remote detection ensures that, regardless of the load current or what kind of circuit board layout, the load voltage regulation is accurate. The LTC7150S's 3.1V to 20V wide input range supports a wide range of applications, including most intermediate bus voltage applications, and is compatible with many types of batteries. The integrated N-channel MOSFET provides up to 20A continuous load current with a minimum thermal derating in the output voltage range of 0.6V to VIN, making it ideal for point-of-load applications such as power supply to high current / low voltage DSP, FPGA and ASIC The Other applications include telecom / data communications systems, distributed power architectures, and general high power density systems.

LTC7150S is very Short 25ns Shortest On Time Allows high step-down power over high frequencies to support operation in forced continuous and discontinuous mode. The operating frequency is optional in the 400kHz to 3MHz range and can be synchronized to an external clock. The LTC7150S has a total differential output voltage accuracy of ± 1% over the -40 ° C to 125 ° C operating junction temperature range. Other features include direct remote differential VOUT sampling at the load, PHMODE phase selector pin, accurate 1.2V RUN pin threshold, VIN overvoltage protection, power good mark and programmable soft start / trace.
