This document introduces LT1680, a high-power, current-mode switching power supply controller optimized for boost topologies. The IC drives an N-channel MOSFET switch for DC/DC converter applications up to 60V input. A high current gate drive output handles up to 10,000pF gate capacitance, enabling the construction of high power DC/DC convert- ers. Current sense common mode range up to 60V allows current sensing to be referenced to the input supply, eliminating the need for sense blanking circuits. The LT1680 incorporates programmable average current limiting allowing accurate limiting of DC current in the magnetics, independent of ripple current . User adjustable slope compensation provides stable operation at duty cycles up to 90%. The LT1680 operating frequency is programmable and can be synchronized up to 200kHz. Minimum off-time operation provides switch protection. The IC also incorpo- rates a soft start feature that is gated by both shutdown and undervoltage lockout conditions.

LM117HV/LM317HV are adjustable 3-terminal positive voltage regulators capable of supplying in excess of 1.5A over a 1.2V to 57V output range. They are exceptionally easy to use and require only two external resistors to set the output voltage. Both line and load regulation are better than standard fixed regulators. The LM117HV is packaged in standard transistor packages which are easily mounted and handled. It offers full overload protection available only in IC’s, including current limit, thermal overload protection, and safe area protection. All overload protection circuitry remains fully functional even if the adjustment terminal is disconnected. Capacitors are not needed unless the device is situated more than 6 inches from the input filter capacitors, in which case an input bypass is needed. An optional output capacitor can be added to improve transient response. The adjustment terminal can be bypassed to achieve very high ripple rejection ratios which are difficult to achieve with standard 3-terminal regulators. Besides replacing fixed regulators, the LM117HV is useful in a wide variety of other applications. Supplies of several hundred volts can be regulated as long as the maximum input to output differential voltage is within the specified range.

The LT3011 is a high voltage, micropower, low dropout linear regulator. The device is capable of supplying 50mA of output current with a dropout voltage of 300mV. Designed for use in battery-powered high voltage systems, the low quiescent current (46μA operating and 1μA in shutdown) is well controlled in dropout, making the LT3011 an ideal choice. The LT3011 includes a PWRGD flag to indicate output regulation. The delay between regulated output level and flag indication is programmable with a single capacitor. The LT3011 also has the ability to operate with very small output capacitors; it is stable with only 1μF on the output. Small ceramic capacitors can be used without the addition of any series resistance (ESR) as is common with other products.

The LM2722 is a high-speed synchronous/asynchronous MOSFET driver designed for use with multi-phase controllers. It differs from the LM2726 by changing the functionality of the SYNC_EN pin to control between synchronous and asynchronous operations. The LM2722 simultaneously drives both top and bottom MOSFETs with a typical 20ns dead time and built-in cross-conduction protection circuitry. Asynchronous operations can be more efficient at very light loads, making it advantageous in portable systems. Each driver of the LM2722 can handle a peak sourcing and sinking current of 3A, and the minimum pulse width is as low as 55ns.

The LTM4600HV is packaged in a low-profile package, allowing for high-density point-to-point regulation using unused space on the bottom of the PCB.

The LTC1564 is a new type of continuous time filter for antialiasing, reconstruction and other band-limiting applications. It has one analog input pin and one analog output pin. The cutoff frequency (fC) and gain are programmable while the shape of the lowpass response is fixed. A latching digital interface stores fC and gain settings or it can be bypassed for control directly from the pins. The LTC1564 operates from 2.7V to 10V total (single or split supplies) and comes in a 16-pin surface mount package.
