POWER
The
LM2576 series of regulators are monolithic integrated circuits ideally suited
for easy and convenient design of a step–down switching regulator (buck
converter). All circuits of this series are capable of driving a 3.0A load with
excellent line and load regulation. Two different versions (one having a fixed
output voltage of 3.3 V, and one with 5.0 V) of this IC are used in the
regulator board.
SERIAL ACCESS CMOS 16K (2048*8) EEPROM ST24C16
The
ST24C16 is a 16Kbit electrically erasable programmable memory (EEPROM),
organised as 8 blocks of 256*8 bits. The memory is compatible with the I²C
standard, two wire serial interface, which uses a bidirectional data bus and
serial clock. The memory carries a built-in 4 bit, unique device identification
code (1010) corresponding to the I²C bus definition. This is used together with
1 chip enable input (E) so that up to 2*8K devices may be attached to the I²C
bus and selected individually.
LM2576
The
LM2576 series of regulators are monolithic integrated circuits ideally suited
for easy and convenient design of a step–down switching regulator (buck
converter). All circuits of this series are capable of driving a 3.0 A load
with excellent line and load regulation.
These
devices are available in fixed output voltages of 3.3 V, 5.0 V, 12 V, 15 V, and
an adjustable output version. These regulators were designed to minimize the
number of external components to simplify the power supply design. Standard
series of inductors optimized for use with the LM2576 are offered by several
different inductor manufacturers.
Since
the LM2576 converter is a switch–mode power supply, its efficiency is
significantly higher in comparison with popular three–terminal linear
regulators, especially with higher input voltages. In many cases, the power
dissipated is so low that no heatsink is required or its size could be reduced
dramatically.
A
standard series of inductors optimized for use with the LM2576 are available
from several different manufacturers. This feature greatly simplifies the design
of switch–mode power supplies.
The
LM2576 features include a guaranteed ±4% tolerance on output voltage within
specified input voltages and output load conditions, and ±10% on the oscillator
frequency (±2% over 0°C to 125°C). External shutdown is included, featuring 80
mA (typical) standby current. The output switch includes cycle–by–cycle current
limiting, as well as thermal shutdown for full protection under fault
conditions.
LM317T
The
LM317T is an adjustable 3 terminal positive voltage regulator capable of
supplying in excess of 1.5 amps over an output range of 1.25 to 37 volts. This
voltage regulator is exceptionally easy to use and requires only two external
resistors to set the output voltage. Further, it employs internal current
limiting, thermal shutdown and safe area compensation, making it essentially
blow–out proof. The LM317 serves a wide variety of applications including
local, on card regulation. This device can also be used to make a programmable
output regulator, or by connecting a fixed resistor between the adjustment and
output, the LM317 can be used as a precision current regulator.
ST24LC21
The
ST24LC21 is a 1K bit electrically erasable programmable memory (EEPROM),
organized by 8 bits. This device can operate in two modes: Transmit Only mode
and I2C bidirectional mode. When powered, the device is in Transmit Only mode
with EEPROM data clocked out from the rising edge of the signal applied on
VCLK. The device will switch to the I2C bidirectional mode upon the falling
edge of the signal applied on SCL pin. The ST24LC21 can not switch from the I2C
bidirectional mode to the Transmit Only mode (except when the power supply is
removed). The device operates with a power supply value as low as 2.5V. Both
Plastic Dual-in-Line and Plastic Small Outline packages are available.
TEA6415
The
main function of the IC is to switch 8 video input sources on 6 outputs. Each
output can be switched on only one of each input. On each input an alignment of
the lowest level of the signal is made (bottom of synch. top for CVBS or black
level for RGB signals). Each nominal gain between any input and output is 6.5dB.
For D2MAC or Chroma signal the alignment is switched off by forcing, with an
external resistor bridge, 5 VDC on the input. Each input can be used as a
normal input or as a MAC or Chroma input (with external resistor bridge). All
the switching possibilities are changed through the BUS. Driving 75Ω load needs
an external transistor. It is possible to have the same input connected to
several outputs. The starting configuration upon power on (power supply: 0 to
10V) is undetermined. In this case, 6 words of 16 bits are necessary to
determine one configuration. In other case, 1 word of 16 bits is necessary to determine
one configuration.
