37VIN, 1.2A, 2.5MHz Step-Down DC/DC Converter Withstands 55V Transients
Linear Technology Corporation announces the LT3686, a 1.2A, 37VIN step-down switching regulator. The LT3686 operates within a VIN range of 3.6V to 37V with overvoltage lockout, protecting the regulator and load from transients as high as 55V, making it ideal for load dump and cold-crank conditions commonly found in automotive applications as well as 24V industrial supplies. Its internal 1.85A switch can deliver up to 1.2A of continuous output cur...
Small Footprint 4V-38V Input Voltage Range Synchronous Step-Down DC/DC Controller
Linear Technology has announced the LTC3854, a tiny 2mm x 3mm DFN-12 packaged, wide input voltage range synchronous step-down switching DC/DC controller that drives all N-channel power MOSFET stages. The 4V to 38V input range addresses a wide variety of applications, including most intermediate bus voltages and battery chemistries. The strong on-board MOSFET gate drivers enable high power external MOSFETs to produce output currents up to 20A with...
Surface Mount 500mA LDO Is Easily Paralleled Without Hot Spots
Linear Technology has announced the LT3085, the latest member of a family of next-generation NPN LDOs that can be easily paralleled for heat spreading and are adjustable down to 0 volts with a single resistor. This new architecture regulator uses a current reference rather than a conventional voltage reference to allow sharing between multiple regulators by directly paralleling the pins. Current sharing is set with a small length of PC trace as b...
Isolated Monolithic Flyback Simplifies Design and Eliminates Optocoupler
Linear Technology has announced the LT3573, an isolated monolithic flyback switching regulator with an integrated 1.25A NPN power switch. The LT3573 significantly simplifies the design of a flyback converter since it does not require a third winding or optoisolator and can sense the output voltage directly from the primary side flyback waveform.
36V Input (60V Transient), 1A Fault Tolerant Step-Down Regulator Requires Only 75uA of Quiescent Current
Linear Technology has announced the LT3695, a fault tolerant 1A, 36V input step-down switching regulator. Its Burst Mode® operation keeps quiescent current under 75µA in no load standby conditions. The LT3695 operates from a 3.6V to 36V input voltage range and can safely sustain transient voltages up to 60V, making it ideal for load dump and cold-crank conditions commonly found in automotive applications. Its 1.45A internal switch can deliver u...

UltraFast - Digitally Programmable 5A LDO Features 85mV Dropout & 25uVRMS Noise
Linear Technology has announced the LT3070, a digitally programmable linear regulator with the lowest dropout voltage, lowest noise and fastest transient response of any monolithic 5A LDO currently available. Dropout voltage at 5A is an ultralow 85mV. Output voltage noise at 5A is only 25uVRMS over a 10Hz to 100kHz bandwidth. The LT3070's 1MHz unity gain bandwidth, coupled with its minimum 15uF ceramic output capacitance, provides a mere 30mV of ...
Dual, 26VIN, 4A DC/DC µModule Regulator in 15mm x 15mm Surface Mount Package
Linear Technology has introduced the LTM4619, a complete dual step-down DC/DC µModule regulator system, including inductors and MOSFETs in a tiny surface mount package. The LTM4619 regulates two output voltages ranging from 0.8V to 5V at up to 4A each from an input supply of 4.5V to 26.5V (28V abs max). The outputs are regulated with 180º out-of-phase operation to minimize input ripple current, thus requiring fewer input capacitors.
