LTC3779規(guī)格書詳情
LTC3779屬于集成電路(IC)的PMIC-穩(wěn)壓器-DCDC開關(guān)式控制器。由亞德諾半導(dǎo)體技術(shù)有限公司制造生產(chǎn)的LTC3779DC-DC 開關(guān)控制器PMIC(電源管理集成電路)DC 到 DC 開關(guān)式控制器是用于高效率電路的穩(wěn)壓 IC,其配置為生成高于(突升或步升)或低于(突降或步降)輸入電源的輸出電源電壓。其他拓?fù)浣Y(jié)構(gòu)可能包括:降壓-升壓、反激、正激、Cuk、SEPIC、全橋、半橋和推挽式。這些器件不同于需要最小電壓并“燒盡”多余電壓的線性穩(wěn)壓器。
DESCRIPTION
The LTC?7878 is a high performance buck-boost switching
regulator controller that operates from an input voltage
above, below or equal to the output voltage. The constant-
frequency, peak current mode architecture allows
a phase-lockable switching frequency of up to 600kHz,
while a programmable input or output current loop regulates
the average input or output current accurately supporting
battery charging applications. With a wide 5V to
70V input and output range and seamless, low noise transitions
between operating regions, the LTC7878 is ideal
for industrial and telecom systems.
The LTC7878 features forced continuous mode (FCM)/
pulse-skipping mode operation. It supports multiphase/
multi-ICs parallel operation for high power applications.
Additional features include 7V N-Channel gate drivers,
smart EXTVCC auxiliary supply and programmable inductor
peak current limit. A PGOOD pin indicates when the
output is within 10 of its designed set point.
The LTC7878 is available in a low profile 32-Lead QFN package.
FEATURES
- Single Inductor Architecture Allows VIN Above, Below or Equal to the Regulated VOUT
- Synchronous Rectification: Up to 98 Efficiency
- Wide VIN Voltage Range: 5V to 70V
- ±1 Output Voltage Accuracy: 1V ≤ VOUT ≤ 70V
- DCR or RSENSE Current Sensing
- Peak Current Mode Control in Buck/Boost/Buck-Boost Mode
- Programmable Input or Output Current Regulation
- 7V NMOS Gate Drivers
- Phase-Lockable Frequency (100kHz to 600kHz)
- Multiphase/Multi-ICs Parallel Operation
- Selectable Continuous or Pulse-Skipping Mode Operation and Inductor Peak Current Limits
- Small 32-Lead 5mm × 5mm QFN Package
APPLICATIONS
- Industrial and Telecom Systems
- Distributed DC Power or Battery Systems
