The UCC1800/1/2/3/4/5, UCC2800/1/2/3/4/5, and UCC3800/1/2/3/4/5 are a family of high-speed, low-power integrated circuits designed for off-line and DC-to-DC fixed frequency current-mode switching power supplies. They feature internal soft start, internal fault soft start, and internal leading-edge blanking of the current-sense signal.

UCC1800/1/2/3/4/5 is a high-speed, low-power integrated circuit that contains all of the control and drive components required for off-line and DC-to-DC fixed frequency current-mode switching power supplies with minimal parts count.

UCC3581 is a voltage mode pulse width modulator designed to control low power isolated DC-DC converters, primarily used for single switch forward and flyback converters. It features BiCMOS circuitry for low startup and operating current, while being able to drive power MOSFETs at frequencies up to 100kHz. The UCC3581 oscillator allows programming of both the frequency and the maximum duty cycle with two resistors and a capacitor. It includes programmable soft start circuitry, overcurrent detection, a 7.5V linear preregulator for controlling chip VDD during startup, and an on-board 4.0V logic supply. The UCC3581 provides functions to maximize light load efficiency that are not normally found in PWM controllers.

The UCC3581 is a voltage mode pulse width modulator designed to control low power isolated DC-DC converters. It features low startup and operating current, programmable minimum and maximum duty cycle, 1A peak source and sink output current, etc.

UCC15701/2 UCC25701/2 UCC35701/2 Advanced Voltage Mode Pulse Width Modulator

The UCC1570 family of pulse width modulators is intended for application in isolated switching supplies using primary side control and a voltage mode feedback loop. Made with a BiCMOS process, these devices feature low startup current for efficient off-line starting with a bootstrapped low voltage supply. Operating current is also very low; yet these devices maintain the ability to drive a power MOSFET gate at frequencies above 500kHz. Voltage feedforward provides fast and accurate response to wide line voltage variation without the noise sensitivity of current mode control. Fast current limiting is included with the ability to latch off after a programmable number of repetitive faults has occurred. This allows the power supply to ride through a temporary overload, while still shutting down in the event of a permanent fault. Additional versatility is provided with a maximum duty cycle clamp programmable within a 20% to 80% range and line voltage sensing with a programmable window of allowable operation.

The UCC3580 family of PWM controllers is designed to implement a variety of active clamp/reset and synchronous rectifier switching converter topologies. It includes an auxiliary switch driver that complements the main power switch and has a programmable deadtime or delay between each transition. The features of this product family include voltage mode control, programmable limits for transformer volt-second product and PWM duty cycle, high current gate driver, multiple protection features, and low supply current.

The document is the datasheet of UCC1580-1,-2,-3,-4 UCC2580-1,-2,-3,-4 UCC3580-1,-2,-3,-4 PWM controllers, introducing the features and characteristics of the product.

The UCC3580 family of PWM controllers is designed to implement a variety of active clamp/reset and synchronous rectifier switching converter topologies. While containing all the necessary functions for fixed frequency, high performance pulse width modulation, the additional feature of this design is the inclusion of an auxiliary switch driver which complements the main power switch, and with a programmable deadtime or delay between each transition. The active clamp/reset technique allows operation of single ended converters beyond 50% duty cycle while reducing voltage stresses on the switches, and allows a greater flux swing for the power transformer. This approach also allows a reduction in switching losses by recovering energy stored in parasitic elements such as leakage inductance and switch capacitance. The oscillator is programmed with two resistors and a capacitor to set switching frequency.

The document describes the features and characteristics of the RI-60 series ultra-miniature dry-reed switch. The switch is hermetically sealed in a gas-filled glass envelope and has a single-pole, single-throw structure with normally open contacts. It can be actuated by an electromagnet, a permanent magnet, or a combination of both. The device is intended for use in relays, sensors, pulse counters, or similar devices.
