ADP3198規(guī)格書詳情
ADP3198屬于集成電路(IC)的特殊用途穩(wěn)壓器。由安森美半導體公司制造生產(chǎn)的ADP3198特殊用途穩(wěn)壓器該系列產(chǎn)品用于電源控制、某種形式的轉(zhuǎn)換,適用于特定的復雜應用。因此,各種產(chǎn)品特性集差異較大,包括空燃比傳感器接口、汽車交流發(fā)電機電壓調(diào)節(jié)、DDR 端接、液體透鏡控制、摩托車轉(zhuǎn)向信號控制、熱電 (peltier) 冷卻器控制、壓電觸覺控制、閥門控制、小型發(fā)動機管理等。
GENERAL DESCRIPTION
The ADP31981 is a highly efficient, multiphase, synchronous buck switching regulator controller optimized for converting a 12 V main supply into the core supply voltage required by high performance Intel processors. It uses an internal 8-bit DAC to read a voltage identification (VID) code directly from the processor, which is used to set the output voltage between 0.5 V and 1.6 V.
This device uses a multimode PWM architecture to drive the logic-level outputs at a programmable switching frequency that can be optimized for VR size and efficiency. The phase relation ship of the output signals can be programmed to provide 2-, 3-, or 4-phase operation, allowing for the construction of up to four complementary buck switching stages.
The ADP3198 also includes programmable no load offset and slope functions to adjust the output voltage as a function of the load current, optimally positioning it for a system transient. The ADP3198 also provides accurate and reliable short-circuit protection, adjustable current limiting, and a delayed power good output that accommodates on-the-fly output voltage changes requested by the CPU.
The ADP3198 has a built-in shunt regulator that allows the part to be connected to the 12 V system supply through a series resistor.
The ADP3198 is specified over the extended commercial temperature range of 0°C to 85°C and is available in a 40-lead LFCSP.
FEATURES
Selectable 2-, 3-, or 4-phase operation at up to 1 MHz per phase
