ON Semiconductor further strengthened its low-dropout (LDO) linear regulator product portfolio and introduced a series of new high-performance devices to support double data rate (DDR) memory.
The NCP51200, NCP51400, NCP51510, and NCP51199 with built-in power MOSFETs are designed for computing, data networking, industrial, and handheld consumer markets for various applications specific to SDRAM DIMM memory, servers, routers, smartphones, tablet platforms, and other set-top boxes , Smart TVs, printers and PC / laptop motherboards. AEC-Q100-compliant versions are also available for automotive applications, including embedded GPS mapping systems, infotainment, and Wifi and Bluetooth communications.
The high-performance LDO supports DDR1, DDR2, DDR3, LPDDR3, DDR4, and LPDDR4 standards, with a terminal voltage (VTT) as low as 500 millivolts (mV). When used with DDR4 and LPDDR4, each chip can actively supply and sink 2.0A of current. In addition, when used with DDR4 and LPDDR4, the NCP51145 can support currents up to 1.2A. NCP / NCV51199 can supply and sink 2A and 1.5A current for DDR2 and DDR3 respectively, while NCP51200 and NCP51510 are specified for 3A peak current operation and support remote sensing.
The highly integrated DDR terminal LDO also benefits from soft start, on-chip thermal shutdown, and (for some devices) undervoltage lockout mechanisms. Each device has a high-speed differential amplifier that provides ultra-fast response to line voltage and load current transients. All these devices are also compatible with DDR1 and DDR2, making it easy to upgrade to newer DDR memory. The company stated that the specified temperature range is -40C to + 125C, and the extended temperature range provided by the car version is + 150C.
Simon Keaton, vice president of integrated circuit products at ON Semiconductor, said: "As connectivity and the Internet of Things (IoT) drive data communications, DDR memory has been widely expanded into many non-traditional products." The comprehensive game-changing product portfolio is suitable for new design projects and can be used as a replacement for existing equipment; but has higher performance and can be upgraded in the future. NCP51400 and NCP51510 are highly advanced ICs that can support First-generation DDR technology, and NCP51145 combines superior performance and attractive price. In addition,
in the extended series of 15 NCP51xxx LDO solutions, three different packaged products are provided, including 8-lead SOIC-EP, 8 2 pin 2 × 2 mm DFN and 10 pin 3 × 3 mm DFN packages.
