Low Voltage Hot Swap Controller with Adjustable Current Limit
Linear Technology has introduced the LTC4218 Hot Swap Controller for protecting boards with load supply voltages ranging from 2.9V to 26.5V. When a board is plugged into a backplane, large inrush currents can create a glitch on the load supply causing other boards on the bus to malfunction. The LTC4218 enables safe board insertion and removal from a live backplane, using an external N-channel pass MOSFET in the power path to limit the inrush curr...
Quad Power Supply Sequencer & Supervisor from Linear
The LTC2928 quad supply sequencer and supervisor from Linear Technology offers the flexibility to configure the power supply turn-on and turn-off sequence, monitor the supplies and diagnose supply failures. The device's simple pin-configuration approach to sequencing requires no firmware and allows the four supplies to be placed in any combination of eight time positions with configurable delay between each.
15A DC/DC uModule Regulator Delivers 50% More Power without Sacrificing Board Area
Linear introduced the LTM4627, a 15A DC/DC uModule® regulator with onboard inductors, MOSFETs and supporting components in a 2.6g, 15mm x 15mm LGA (land grid array) package. Circuit design enhancements lower gate capacitance MOSFETs and stronger MOSFET drivers enable the LTM4627 to operate at approximately 7% higher efficiency or to deliver up to 15A load current in the same board area and junction temperature as the 10A DC/DC uModule regulato...
Hot Swap Controller Protects Dual Supplies
Linear Technology has introduced the LTC4222 dual Hot Swap controller for protecting boards with multiple load supply voltages ranging from 2.9V to 29V. When a board is plugged into a backplane, inrush currents can be large enough to create a glitch on the load supply, causing other boards on the bus to malfunction. The LTC4222 enables safe board insertion and removal from a live, two-supply backplane by controlling external N-channel MOSFETs to ...
Integrated 5Amp MOSFET & RSENSE Provides Highly Integrated Hot Swap Solution
Linear Technology introduced the LTC4219 5A Hot Swap controller for protecting low power boards with load supply voltages ranging from 2.9V to 15V. The LTC4219 allows a board to be safely inserted and removed from a live backplane by limiting the amount of inrush current to the load supply during power up. Hot Swap controllers typically call for a number of supporting components. However, the LTC4219 integrates a power MOSFET and sense resistor i...
1.2A Overvoltage/Overcurrent Protector Isolates Sensitive Low Voltage Electronics from Input Power Surges
Linear Technology Corporation introduces the LTC4362, a 2.5V to 5.5V overvoltage and overcurrent protector 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 a device's power input. Inadvertently plugging the wrong power adapter into a device can potentially cause damage from ...
Supply Protection Controller Guards Against Overvoltage, Undervoltage & Reverse Polarity Faults
Linear Technology introduced the LTC4365, an overvoltage (OV), undervoltage (UV) and reverse protection controller, with a -40V to 60V protection range, for applications that require windowed supply protection. The LTC4365 provides two comparator inputs to configure the OV and UV set points within the normal operating range of 2.5V to 34V using an external resistive divider. A gate pin controls a dual N-channel MOSFET to ensure only voltages wit...
Floating Surge Stopper Provides Unlimited Overvoltage Protection
Linear Technology Corporation introduces the LTC4366, an overvoltage protection controller for electronic systems. Operating from 9V to greater than 500V, the LTC4366 floating surge stopper utilizes an adjustable floating topology to enable very high voltage operation independent of the voltage rating of the LTC4366’s internal circuitry.
2.2V Input High Power Step-Down DC/DC Controller
Linear Technology has introduced the LT3740, a high output power step-down synchronous controller that operates from very low input voltages without needing an auxiliary 5V gate drive supply. In addition to a DC/DC step-down controller, the LT3740 integrates a DC/DC step-up converter for generating its own MOSFET gate drive voltage. This function permits the use of inexpensive off-the-shelf 5V gate-drive N-channel MOSFETs, offering up to 3% highe...
Multiphase Step-Down DC/DC Controller with Differential Output Voltage Sensing & PLL
Linear Technology has introduced the LTC3811, a dual output synchronous step-down DC/DC controller with multiphase operation, differential output voltage sensing and integrated phase-lock loop (PLL) synchronization. Up to 12 phases can be paralleled and clocked out-of-phase to minimize the input and output filtering requirements for high current applications (up to 200A). The differential amplifier provides true remote output voltage sensing, ena...
