UC2842BD1G規(guī)格書(shū)詳情
UC2842BD1G屬于集成電路(IC)的PMIC-穩(wěn)壓器-DCDC開(kāi)關(guān)式控制器。由安森美半導(dǎo)體公司制造生產(chǎn)的UC2842BD1GDC-DC 開(kāi)關(guān)控制器PMIC(電源管理集成電路)DC 到 DC 開(kāi)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(xiàn)性穩(wěn)壓器。
The UC3842B, UC3843B series are high performance fixed
frequency current mode controllers. They are specifically designed for
Off?Line and DC?DC converter applications offering the designer
a cost?effective solution with minimal external components. These
integrated circuits feature a trimmed oscillator for precise duty cycle
control, a temperature compensated reference, high gain error
amplifier, current sensing comparator, and a high current totem pole
output ideally suited for driving a power MOSFET.
Also included are protective features consisting of input and
reference undervoltage lockouts each with hysteresis, cycle?by?cycle
current limiting, programmable output deadtime, and a latch for single
pulse metering.
These devices are available in an 8?pin dual?in?line and surface
mount (SOIC?8) plastic package as well as the 14?pin plastic surface
mount (SOIC?14). The SOIC?14 package has separate power and
ground pins for the totem pole output stage.
The UCX842B has UVLO thresholds of 16 V (on) and 10 V (off),
ideally suited for off?line converters. The UCX843B is tailored for
lower voltage applications having UVLO thresholds of 8.5 V (on) and 7.6 V (off).
Features
? Trimmed Oscillator for Precise Frequency Control
? Oscillator Frequency Guaranteed at 250 kHz
? Current Mode Operation to 500 kHz
? Automatic Feed Forward Compensation
? Latching PWM for Cycle?By?Cycle Current Limiting
? Internally Trimmed Reference with Undervoltage Lockout
? High Current Totem Pole Output
? Undervoltage Lockout with Hysteresis
? Low Startup and Operating Current
? This is a Pb?Free and Halide?Free Device
