LINFINITY SG5768/SG5770/SG5772/SG5774/SG6506/SG6507/SG6508/SG6509 handbook
LINFINITY SG6100/SG6511/SG6101/SG6510 handbook
The SG6100/SG6511 and SG6101/SG6510 diode arrays are monolithic, high breakdown, fast switching speed diode arrays. The SG6100/SG6511 is configured with 7 straight through diodes, while the SG6101/SG6510 has 8 straight through diodes. These two diode array configurations allow the designer maximum flexibility for circuit design and board layout. Since each diode within the array has individual anode and cathode connections the device may be used in a variety of applications. Also, due to the array's monolithic construction the diode electrical parameters are very closely matched. Both devices are available in ceramic DIP and flatpack and can be processed to Linfinity's S level, JANTXV, JANTX, or JAN equivalent flows.

LINFINITY LX1570/1571 handbook
LX157xCM/xCDM/xIM/xIDM/xMY series power controller is a secondary-side regulator for isolated auxiliary or secondary power supplies. The series has the advantages of low cost, low saturation voltage of switching devices, low peak current stress on the primary switch, high operating frequency, small output inductor, etc. The series is widely used in multiple output non-isolated switching power supplies, such as desktop computers, as well as telecommunications applications.
LINFINITY SG1842/SG1843 Series CURRENT MODE PWM CONTROLLER PRODUCTION DATA SHEET
The SG1842/SG1843 series is an offline power controller product with features such as low start-up current, automatic feed forward compensation, trimmed oscillator discharge current, pulse-by-pulse current limiting, etc.
LINFINITY LX1681/1682 DATA SHEET
LX1681/1682 are monolithic pulse-width modulator controller ICs, designed to implement a flexible, low cost buck (step-down) regulator supply with minimum external components. The LX1681 is a non-synchronous controller; the LX1682 has a synchronous driver for higher efficiency. The output voltage is adjustable by means of a resistor divider to set the voltage between 1.25V and 4.5V. Short-circuit current limiting can be implemented without expensive current sense resistors. Current is sensed using the voltage drop across the RDS(ON) of the MOSFET — sensing is delayed for 1µs to eliminate MOSFET ringing errors. Hiccup-mode fault protection reduces average power to the power elements during short-circuit conditions. Switching frequency is fixed at 200kHz for optimal cost and space. Under-voltage lockout and soft-start for optimal start-up performance. The LX1681/82 can be disabled by pulling the soft-start pin to ground. Small 8-pin SOIC packaging reduces board space. Optimized for 5V-to-3.3V or 5V-to-2.5V conversion, the LX1681/82 can also be used for other voltage conversions.
LINFINITY LX8580 Data Sheet
The LX8580 is a high-performance, very low dropout voltage regulator, designed for use with advanced microprocessors. This product can be used with separate voltage supplies for the control and power sections, allowing a power section dropout voltage as low as 100mV. The LX8580 can also be used in a single voltage supply configuration, with a dropout performance similar to that of the LX8584 (1.3V at 7A). The LX8580 is supplied in a five-terminal TO-220 package.
LINFINITY SG120 DATA SHEET
The SG120 series is a type of negative voltage regulator that offers self-contained, fixed-voltage capability with up to 1.5A of load current. It comes with a variety of output voltages and four package options, making it an ideal complement to the SG7800A/7800/120 line of three-terminal regulators. All protective features such as thermal shutdown, current limiting, and safe-area control have been incorporated into these units. These regulators require only a single output capacitor or a capacitor and a minimum load of 5mA for satisfactory performance, ensuring ease of application. Although designed as fixed-voltage regulators, the output voltage can be increased using a simple voltage divider. The low quiescent drain current of the device ensures good regulation when this method is used, especially for the SG120 series. By utilizing an improved Bandgap reference design, issues commonly associated with zener diode references, such as output voltage drift and significant changes in line and load regulation, have been eliminated. These devices are available in TO-257 (hermetically sealed TO-220), both isolated and non-isolated, as well as TO-3, TO-39, and TO-66 power packages.
LINFINITY SG7900A/SG7900 SERIES handbook
The SG7900A/SG7900 series of negative regulators offer self-contained, fixed-voltage capability with up to 1.5A of load current. With a variety of output voltages and four package options this regulator series is an optimum complement to the SG7800A/SG7800, SG140 line of three terminal regulators. These units feature a unique band gap reference which allows the SG7900A series to be specified with an output voltage tolerance of ±1.5%. The SG7900A versions also offer much improved line regulation characteristics. All protective features of thermal shutdown, current limiting, and safe-area control have been designed into these units and since these regulators require only a single output capacitor (SG7900 series) or a capacitor and 5mA minimum load (SG120 series) for satisfactory performance, ease of application is assured. Although designed as fixed-voltage regulators, the output voltage can be increased through the use of a simple voltage divider. The low quiescent drain current of the device insures good regulation when this method is used, especially for the SG120 series. These devices are available in hermetically sealed TO-257, TO-3, TO-39 and LCC package.
