产品描述 (功能) : push-pull PWM Controller

General Description
The MIC3808 and MIC3809 are a family of complementary output push-pull PWM control ICs that feature high speed and low power consumption. The MIC3808/9 are ideal for telecom level (36V to 75V) isolated step down dc/dc conversion applications where high output current, small size, and high efficiency are required.
The dual-ended push-pull architecture of the MIC3808/9 allows more efficient utilization of the transformer than single ended topologies, allowing smaller size dc/dc solutions.
Additionally, the out-of-phase push-pull topology allows a higher effective duty cycle, reducing input and output ripple as well as stress on the external components. The dead-time between the two outputs is adjustable between 60ns to 200ns, limiting the duty cycle of each output stage to less than 50%.
The MIC3808/9 are built on a low-power, high-speed BiCMOS process. The 130µA start-up current and 1mA run-current reduce the size of the start-up circuitry and allow high efficiency even at light loads. The high-speed internal 4MHz error amplifier allows MIC3808/9 operation up to 1MHz.
The MIC3808 has a turn-on threshold of 12.5V whereas the MIC3809 has a lower turn-on threshold of 4.3V. Both devices are available in SOP-8 and MSOP-8 package options with an operating range of –40°C to +85°C.

Features
• Dual output drive stages in push-pull configuration
• Leading edge current-sense blanking
• 130µA typical start-up current
• 1mA typical run current
• Operation to 1MHz
• Internal soft start
• On-chip error amplifier with 4MHz gain bandwidth product
• On-chip VDD clamping

   • Half bridge converters
   • Full bridge converters
   • push-pull converters
   • Voltage-fed push-pull converters

产品描述 (功能) : push-pull Connectors
1. "A LITTLE GIANT"
The most compact HR10 series is as slender as a cigarette but it fits every application with well-balanced, simplified
layout in limited space.
2. Easy "push-pull" OPERATION
One touch "push-pull" coupling mechanism assures easy and quick connecting and disconnecting. You can couple it
accurately just by pushing any part of the connector housing.
3. Polarization

4. Protection of connection pin
A connector pin is located to avoid any damage which may be caused when blind mating.
5. High density
The space-saving "push-pull" mechanism facilitates multi-installation of connectors.
6. Easy wiring and mounting
No use of screws makes wireing and mounting easier.

产品描述 (功能) : Single Push Button Controlled Potentiometer (XDCP™) linear, 32 Taps, Push Button Controlled, Terminal Voltage ±5V

DESCRIPTION
The Intersil X9511 is a push button controlled potentiometer that is ideal for push button controlled resistance trimming.
The X9511 is a resistor array composed of 31 resistive elements. Between each element and at either end are tap points accessible to the wiper element. The position of the wiper element is controlled by the PU and PD inputs. The position of the wiper can be automatically stored in E2 memory and then be recalled upon a subsequent power-on operation.
The resolution of the X9511 is equal to the maximum resistance value divided by 31. As an example, for the X9511W (10kΩ) each tap point represents 323Ω.
All Intersil nonvolatile products are designed and tested for applications requiring extended endurance and data retention.
