High-frequency, triple-output synchronous converter maintains outputs during automotive cold cranking
Analog Devices announces the Power by Linear LTC7815, a high frequency (up to 2.25MHz) triple output (buck, buck, boost), synchronous converter that maintains all output voltages in regulation during automotive cold crank conditions. A 12V automotive battery can droop to less than 4 volts during engine restart or cold crank, causing reset of infotainment systems and […]
DC/DC controller merges switched-capacitor circuit, synchronous step-down controller to shrink package size
Analog Devices, Inc. today announced the Power by Linear LTC7821, an industry first hybrid step-down synchronous controller that merges a switched capacitor circuit with a synchronous step-down controller, enabling up to a 50% reduction in DC/DC converter solution size compared to traditional step-down solutions. This improvement is enabled by a three times higher switching frequency without compromising efficiency. […]
