2.5A Monolithic Active Cell Balancer with Telemetry Interface

Mon, 16 Dec 2013 12:10:46 -0600

MILPITAS, CA – December 16, 2013 – Linear Technology Corporation announces the LT8584, a monolithic flyback DC/DC converter designed to actively balance high voltage stacks of batteries. These battery stacks are commonly found in electric and hybrid vehicles as well as fail-safe power supplies and energy storage systems. Because these batteries are stacked in series, the lowest capacity battery will limit the entire battery stack’s run-time. Ideally, the batteries would be perfectly matched, but this is often not the case and generally gets worse as the batteries age. Passive energy balancing offers no improved run-time as it dissipates the added energy of the higher capacity batteries to match the lowest one. Conversely, the LT8584 offers high efficiency active balancing, which redistributes the charge from the stronger cells (higher voltage) to charge the weaker cells during discharge. This enables the weaker cells to continue to supply the load, extracting 96% of the entire stack capacity where passive balancing usually extracts approximately 80%.

10A µModule Step-Down Regulator Delivers Full Current with 86% Efficiency at up to 83°C Ambient

Mon, 01 Jul 2013 12:25:26 -0500

MILPITAS, CA – June 27, 2013 – Linear Technology Corporation announces the LTM4649, a 10A step-down µModule® regulator with high operating efficiency and low temperature rise in a 9mm x 15mm x 4.92mm BGA (ball grid array) package. The LTM4649 requires no heat sink, airflow or output current derating at full power from 0°C to 83°C ambient temperature, while operating up to 86% efficiency (5VIN –12VIN, 1.5VOUT at 10A). Output current is reduced only by 4A up to 100ºC ambient and by 2A with 400LFM. The LTM4649 converts input supplies ranging from 4.5V to 16V to lower output voltages ranging from 0.6V to 3.3V. Equipped with a differential remote sense amplifier to compensate for voltage droop due to circuit board trace impedance, the LTM4649 regulates a load voltage with ±1.5% accuracy over line, load and temperature (-40°C to 125°C).

40V, 1.5A Robust Linear Regulator Has Current & Temperature Monitor Outputs

Mon, 24 Jun 2013 10:28:09 -0500

MILPITAS, CA – June 24, 2013 – Linear Technology Corporation announces the LT3081, a rugged 1.5A wide input voltage range linear regulator with key usability, monitoring and protection features. The device has an extended safe operating area (SOA) compared to existing regulators, making it ideal for high input-to-output voltage and high output current applications where older regulators limit the output. The LT3081 uses a current source reference for single resistor output voltage settings and output adjustability down to “0.” Output current limit can be set externally with a single resistor. This regulator architecture, combined with low millivolt regulation, enables multiple ICs to be paralleled easily for heat spreading and higher output current. The current from the device’s current monitor can be summed with the set current for line-drop compensation, where the output of the LT3081 increases with current to compensate for line drops.
