| CA3420AT/3 CA3420AT/3 PDF The LA7875N, LA7876N are designed for use in internet TVs and high-resolution CRT monitors that require a narrow vertical return period. These ICs succeed in achieving a narrow vertical return period by adopting a new 3 pump-up technique in the voltage pump-up circuit. Since this allows the use of a reference voltage lower than that used with the 2 pump-up technique, the LA7875N, LA7876N achieve a significant reduction in power dissipation. Also, since the bus control system signal- processing IC can control these ICs and these ICs can directly drive the deflection yoke for all frequencies down to DC from the sawtooth wave output, shift operation, which is required for wide aspect ratio television, can be controlled from the bus. Since the LA7875N has a maximum deflection output current of 2.2 A p-p, it is appropriate for use in medium-size CRTs. Since the LA7876N has a maximum deflection output current of 3 A p-p, it is appropriate for use in larger CRTs. CA3420AT/3 Datasheet The CA3420AT/3 center tap Schottky rectifier has been expressly designed to meet the rigorous requirements of hi- rel environments. It is packaged in the hermetic isolated TO-257AA package. The device's forward voltage drop and reverse leakage current are optimized for the lowest power loss and the highest circuit efficiency for typical high frequency switching power supplies and resonent power converters. Full MIL-PRF-19500 quality conformance testing is available on source control drawings to TX, TXV and S quality levels.

While this uses more current than a series-connected RC, it provides a linear ramp voltage on the capacitor which is also used as a reference for the comparator. The charging current is equal to OFF Programmable LUT(1.0 std.) C-mount (use>2/3" format lenses) 12V DC10%, 500 mA (current measured at 25) -10C to 45C* 7Grms (10 Hz to 2000 Hz) Random 70G 44mm x 44mm x 64mm (1.73" x 1.73" x 2.51") 133 grams, 4.7 oz (without tripod) Note 1: Absolute Maximum Ratings are limits beyond which damage to the device may occur. For guaranteed performance limits and associated test conditions, see the Electrical Characteristics tables. Note 2: See Circuit in Typical Applications. To ensure constant junction temperature, low duty cycle pulse testing is used. Note 3: Limits appearing in boldface type apply over the entire junction temperature range for operation. Limits appearing in normal type apply for TA = TJ = 25C. Note 4: The junction-to-ambient thermal resistance are as follows: 195C/W for the TO-92 (N) package, 160C/W for the molded plastic SO-8 (S), 50C/W for the TO-220 package and 73C/W for the TO-263 package. If the TO-220 package is used with a heat sink, JA is the sum of the package thermal resistance junction-to- case of 3C/W and the thermal resistance added by the heat sink and the thermal interface. The thermal resistance of the TO-263 package can be reduced by increasing the PCB copper area thermally connected to the package: using 0.5 square inches of copper area, ϕ JA is 50C/W; with 1 square inch of copper area ϕ JA is 37C/W; and with 1.6 or more square inches of copper area ϕ JA is 32C/W. Hold (HOLD) HOLD is used in conjunction with the CS pin to select the device. Once the part is selected and a serial sequence is underway, HOLD may be used to pause the serial communication with the controller (without reset- ting the serial sequence). To pause, HOLD must be |
