- Conditioning a Switch-mode Power Supply Current Signal Using TI Op AmpsPDF, 61 Kb, Archivo publicado: marzo 23, 2000
The switch-mode power supply primary current is often sensed using a power resistor. Using an op amp to amplify the current-sense signal can reduce cost and improve noise performance and efficiency. This report reviews the advantages of using an op amp circuit and analyzes the design criteria needed to choose the proper op amp. - U-133A UCC3800/1/2/3/4/5 BiCMOS Current Mode Control IC'sPDF, 583 Kb, Archivo publicado: sept 5, 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 - U-111 Practical Considerations in Current Mode Power SuppliesPDF, 787 Kb, Archivo publicado: sept 5, 1999
This application note explains the numerous PWM functions and ways to maximize their usefulness. It covers practical circuit design considerations such as slope compensation gate drive circuitry external control functions synchronization and paralleling current-mode controlled modules. Circuit diagrams and simplified equations are included. - UCC38C42 Family of High-Speed BiCMOS Current-Mode PWM ControllersPDF, 280 Kb, Archivo publicado: feb 7, 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 Kb, Archivo publicado: sept 5, 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. A)PDF, 363 Kb, Revisión: A, Archivo publicado: mayo 28, 2002
- DN-62 Switching Power Supply Topology Voltage Mode vs. Current ModePDF, 66 Kb, Archivo publicado: sept 5, 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. - Differences Between the UCC3813 and the UCC3800 PWM FamiliesPDF, 27 Kb, Archivo publicado: jun 2, 2000
This application report discusses the parametric differences between the UCC3813 and UCC3800 PWM families of integrated circuits available from Texas Instruments.
