38VIN Dual Synchronous Step-Down DC/DC Controller with 1% Accurate Pin-Selectable Output Voltages
Linear Technology Corporation announces the LTC3865/-1, a 95% efficient, dual output synchronous step-down DC/DC controller with 2-pin selectable VOUT programming, a feature that saves 4 precision feedback resistors. The output voltages maintain a tight ±1% accuracy including initial set-point, a -40°C to 125°C operating temperature range and load/line regulation. Nine selectable output voltages ranging from 0.6V to 5V are possible. The 4.5V t...
LT3758-100V Input DC/DC Controller Generates Positive or Negative Regulated Output
Linear Technology has announced the LT3758, a high input voltage DC/DC controller for boost, flyback, SEPIC and inverting power supply applications, capable of generating either positive or negative regulated output voltages. The LT3758 has two voltage feedback error amplifiers and reference voltages. One set is for positive output voltages, the other is for negative output voltages, both off a single feedback pin, making the LT3758 a highly vers...
Triple Output, Buck/Buck/Boost Synchronous DC/DC Controller Targets Automotive Start/Stop Systems
Linear Technology Corporation introduces the LTC3859, a triple output (buck, buck, boost), low quiescent current synchronous DC/DC controller that maintains all output voltages in regulation during automotive cold crank conditions. A 12V car battery can droop to less than 4 volts during engine restart or cold crank, causing reset of infotainment systems and other electronics that operate from 5 volts and higher. The high efficiency synchronous bo...
LTC4361 - Overvoltage/Overcurrent Protection Controller Safeguards Sensitive Low Voltage Electronics from Input Power Surges
Linear Technology Corporation introduces the LTC4361, a 2.5V to 5.5V overvoltage and overcurrent protection controller designed to safeguard low voltage, portable electronics from damaging input voltage transients and current surges. Overvoltage events can occur due to power adapter failure or faults, or when hot-plugging an AC adapter into the power input of the device. The wrong power adapter can also inadvertently be plugged into a device, pot...
Complete DC/DC µModule Regulator Delivers Dual 8A Outputs from up to 26.5VIN
Linear Technology has introduced the LTM4628, µModule regulator containing two step-down 8A DC/DC converter circuits with the inductors, MOSFETs and other necessary components in a 15mm x 15mm x 4.32mm LGA package.
