General Description
The AP2014 controller IC is designed to provide a low cost synchronous Buck regulator for on-board DC to DC converter applications. With the migration of today’s ASIC products requiring low supply voltages such as 1.8V and lower, together with currents in excess of 3A, traditional linear regulators are simply too lossy to be used when input supply is 5V or even in some cases with 3.3V input supply. The AP2014 together with dual N-channel MOSFETs such as AF9410, provide a low cost solution for such applications. This device features an internal 200KHz oscillator (400KHz for "A" version), under-voltage lockout for both Vcc and Vc supplies, an external programmable soft-start function as well as output under-voltage detection that latches off the device when an output short is detected.

Features
*Synchronous Controller in 8-Pin Package
*Operating with single 5V or 12V supply voltage
*Internal 200KHz Oscillator (400KHz for AP2014A)
*Soft-Start Function
*Fixed Frequency Voltage Mode
*500mA Peak Output Drive Capability
*Protects the output when control FET is shorted
*SOP-8L/PDIP-8L Pb-Free package

Applications
*Graphic Card
*Hard Disk Drive
*DDR memory source sink Vtt application
*Low cost on-board DC to DC such as 5V to 3.3V, 2.5V or 1.8V

These devices feature very low quiescent current (typ.75μA), and very low dropout voltage (typ.45mV at light loads and 380mV at 100mA) thus prolonging battery life. The quiescent current increases only slightly in dropout. The LP2950/LP2951 has positive transient protection up to 60V and can survive unregulated input transient up to 20V below ground.
The LP2950 and LP2951 were designed to include a tight initial tolerance (typ. 0.5%), excellent load and line regulation (typ. 0.05%), and a very low output voltage temperature coefficient, making these devices useful as a low-power voltage reference. The LP2950 is offered in the 3-pin TO-92 package. LP2951 is available in 8-pin plastic SOIC and DIP packages and offers three major additional system features. An error flag output warns of a low output voltage, often due to failing batteries on input. The LP2951 also features the logic-compatible shutdown input which enables the regulator to be switched on and off.
The LP2951 device may be pin-strapped for a 5V, 3.3V, or 3V output, or programmed from 1.24V to 29V with an external pair of resistors.

GENERAL DESCRIPTION
The ALD1702/ALD1703 is a monolithic operational amplifier intended primarily for a wide range of analog applications in +5V single power supply and ±5V dual power supply systems as well as +4V to +12V battery operated systems. All device characteristics are specified for +5V single supply or ±2.5V dual supply systems. It is manufactured with Advanced Linear Devices' enhanced ACMOS silicon gate CMOS process.
The device is designed to offer a balanced trade-off of performance parameters providing a wide range of desired specifications. It offers the industry pin configuration of mA741 and ICL7611 types.
The ALD1702/ALD1703 has been developed specifically with the 5V single supply or ±2.5 dual supply user in mind. Several important characteristics of the device make many applications easy to implement for these supply voltages. First, the operational amplifier can operate with rail to rail input and output voltages. This feature allows numerous analog serial stages to be implemented without losing operating voltage margin. Secondly, the device was designed to accommodate mixed applications where digital and analog circuits may work off the same 5V power supply. Thirdly, the output stage can drive up to 400pF capacitive and 5KW resistive loads in non-inverting unity gain connection and double the capacitance in the inverting unity gain mode.
These features, coupled with extremely low input currents, high voltage gain, useful bandwidth of 1.5MHz, slew rate of 2.1V/ms, low power dissipation, low offset voltage and temperature drift, make the ALD1702/ALD1703 a truly versatile, user friendly, operational amplifier.
The ALD1702/ALD1703 is designed and fabricated with silicon gate CMOS technology, and offers 1pA typical input bias current. On-chip offset voltage trimming allows the device to be used without nulling in most applications. The device offers typical offset drift of less than 7mV/°C which eliminates many trim or temperature compensation circuits. For precision applications, the ALD1702 is designed to settle to 0.01% in 8ms.
