Application Notes
- Dual Output Boost ConverterPDF, 248 Кб, Файл опубликован: 9 апр 2003
The boost converter is modified to provide bipolar 12-V outputs from 5-V supply. Using the UCC3803 to control the basic boost converter building block, the -12-V outputs are generated using a coupled inductor and a flying capacitor. Output voltage regulation and efficiencies are compared and presented. - DN-54 Innovative Buck Regulator Uses High Side N-Channel Switch Without ComplexPDF, 51 Кб, Файл опубликован: 5 сен 1999
This application note shows how the innovative UCC3803 BiCMOS PWM controller provides very high efficiency without complex gate drives by using a high-side N-channel switch. It converts +5 VDC to +3.3 VDC (or others) and draws only 40 microamps in standby mode. - DN-46 Highly Efficient Low Power DC to DC Inverter Converts +5V Input to -3V OutPDF, 58 Кб, Файл опубликован: 5 сен 1999
This design note describes a flyback inverter application using the UCC3805. The application performs three functions: control, switching, and output rectification. A circuit schematic and a list of materials are included. - DN-56A, Single Switch Flyback Circuit Converts + 5 V to +/- 12 V for RS-232/422PDF, 66 Кб, Файл опубликован: 5 сен 1999
A bipolar 12V supply from a single +5V input can be developed using a number of conventional approaches. A boost converter is the most logical for the +12V output; however, it cannot be used in some interface-circuit applications. One significant drawback of the boost topology is that, even with the boost converter off, the output voltage approaches the input voltage and does not go to zero. This - DN-48 Versatile Low Power SEPIC Converter Accepts Wide Input Voltage RangePDF, 60 Кб, Файл опубликован: 5 сен 1999
This design note describes an output converter for battery-powered and automotive applications. It uses a UCC3803 BiCMOS current-mode controller to provide a 5V output at full load of 100mA from an input of 2.5-13.5V after an initial startup at 5V. The UC3803 is part of the UCC1800/1/2/3/4/5 family of high-speed, low-power integrated circuits, which contains all necessary control and drive compone - DN-43 Simple Techniques to Generate a Negative Voltage Bias SupplyPDF, 38 Кб, Файл опубликован: 5 сен 1999
A low-power negative supply voltage can be developed from a positive input supply using some very common PWM control ICs. Typical applications include generating a -5V to -12V supply for analog function ICs (OP amps), RS-232 communication circuits, and MOSFET or IGBT gate drives at power levels below a few watts. This design note describes a low-power negative output voltage +5 to ?5V inverter usi - Differences Between the UCC3813 and the UCC3800 PWM FamiliesPDF, 27 Кб, Файл опубликован: 2 июн 2000
This application report discusses the parametric differences between the UCC3813 and UCC3800 PWM families of integrated circuits available from Texas Instruments. - U-133A UCC3800/1/2/3/4/5 BiCMOS Current Mode Control IC'sPDF, 583 Кб, Файл опубликован: 5 сен 1999
The UCC3800 IC has several innovative features for general purpose current-mode controlled applications: high speed circuitry, undervoltage lockout, an op-amp type error amplifier, fast overcurrrent protection, a precision reference and a high-current totem-pole output. The popular UC3842 control-circuit architecture has been recently improved to deliver even higher levels of protection and perfor - DN-65 Considerations in Powering BiCMOS ICsPDF, 100 Кб, Файл опубликован: 5 сен 1999
Bipolar linear integrated circuits have been with us for years in the form of PWM and PFC controllers supervisory circuits and other circuits. Since these devices have traditionally used relatively high-voltage (35V) bipolar processes powering was not a concern. In addition many of these ICs contained high-current protection zeners to keep higher voltages from damaging the devices. With a numb - DN-62 Switching Power Supply Topology Voltage Mode vs. Current ModePDF, 66 Кб, Файл опубликован: 5 сен 1999
This design note explains the differences between voltage-mode and current-mode switching power supply topologies. It includes a circuit diagram for each mode and suggests criteria for choosing which mode to use. - UCC38C42 Family of High-Speed BiCMOS Current-Mode PWM ControllersPDF, 280 Кб, Файл опубликован: 7 фев 2002
Since their introduction in the mid 1980?s the bipolar UC3842 family of Pulse width modulation (PWM)controllers has grown to become the most widely-used control strategy in the power supply industry. [1] The reasons for success are quite clear the devices feature an elegantly simple yet very effective control architecture they use only 8 pins they can drive MOSFET gates directly and they offer - DN-42A Design Considerations for Transitioning from UC3842 to the New UCC3802PDF, 42 Кб, Файл опубликован: 5 сен 1999
The UCC3802 offers numerous advantages that allow the power supply design engineer to meet requirements for lower power for battery-operated equipment higher switching frequencies for reduced magnetics size higher levels of circuit integration for improved reliability and lower cost. The UCC3802 family of devices is pin-out compatible with the UC3842 and UC3842A families; however it is not plu - Understanding Buck-Boost Power Stages in Switchmode Power Supplies (Rev.
