The LPS110 series is a 110W power adapter from ASTEC brand. It supports 85-264 VAC 120-300 VDC input voltage range and has features such as high efficiency, built-in EMI filter, low output ripple, adjustable output, power failure, overvoltage protection, and overload protection.

The AS2842 family of control ICs provide pin-for-pin replacement of the industry standard UC3842 series of devices. The devices are redesigned to provide significantly improved tolerances in power supply manufacturing. The 2.5 V reference has been trimmed to 1.0% tolerance. The oscillator discharge current is trimmed to provide guaranteed duty cycle clamping rather than specified discharge current. The circuit is more completely specified to guarantee all parameters impacting power supply manufacturing tolerances. In addition, the oscillator and flip-flop sections have been enhanced to provide additional performance. The RT/CT pin now doubles as a synchronization input that can be easily driven from open collector/open drain logic outputs. This sync input is a high impedance input and can easily be used for externally clocked systems. The new flip-flop topology allows the duty cycle on the AS2844/5 to be guaranteed between 49 and 50%. The AS2843/5 requires less than 0.5 mA of start-up current over the full temperature range.

AS432 1.24V Precision Adjustable Shunt Reference is a precision adjustable shunt reference from Ptcc company. It has temperature compensation, 0.25% to 2.0% bandgap, internal amplifier with 150mA capability, multiple temperature ranges, low frequency dynamic output impedance less than 150mΩ, low output noise.

The LPS40 series is a 40 watts AC to DC power supply with a universal input range of 85-264 VAC and 120-300 VDC. It features a 3” x 5” footprint, remote sense, built-in EMI filter, low output ripple, adjustable output, overvoltage protection, overload protection, 110 KHz switching frequency, and an LPX40 enclosure kit available.

The AS2431 is a three-terminal adjustable shunt regulator providing a highly accurate bandgap reference. The adjustable shunt regulator is ideal for a wide variety of linear applications that can be implemented using external components to obtain adjustable currents and voltages. The AS2431 is a direct replacement for the AS431 in low voltage, low current applications.

The AS432 is a three terminal adjustable shunt regulator utilizing an accurate 1.24V bandgap reference. The AS432 is functionally similar to an AS431 except for its lower reference voltage, making it usable in a wide variety of low voltage applications. Because of its robust bipolar technology, the AS432 handles a wide range of current, and holds off more than 18V so its use is not limited to low power, low voltage systems. Significant care has been taken to provide adequate AC bandwidth to allow the AS432 as an amplifier in control systems and power electronics.
