High efficiency DC-DC converters target automotive applications
The key capabilities of the new DC-DC converters include flexibility for a wide range of output voltages and optimized for high efficiency power conversion with low RDSON integrated synchronous switches. The EcoSpeed ICs operate at up to 90 percent high efficiency capability and a wide input voltage range of 4.5V to 40V. The DC-DC synchronous switching regulators are fully integrated power switches with internal compensation and full fault protection. The switching frequency of 2.2 MHz is compatible with automotive requirements enabling the use of smaller filter components resulting in reduced board space and reduced bill of materials (BOM) costs.
“Semtech’s new EcoSpeed ICs provide optimized performance with heavy-duty, automotive qualification,” said Francois Ricodeau, Product Line Manager for Semtech’s Power and High-Reliability Products Group. “Our EcoSpeed DC-DC converter platform now provides a reduction in board real estate, lower overall system cost and ease of design that make the DC-DC synchronous switching regulators a robust solution for automotive applications.”
The devices have current mode PWM control with PFM mode for improved light load efficiency and a continuous output current up to: 1A for TS30041Q and 2A for TS30042Q, with full protection for over-current, over-temperature, and VOUT over-voltage. They consume less than 10uA in standby mode with low external component count and are available in a compact: 16-pin QFN (3 mm x 3 mm) package for reduced footprint
The TS30041Q and TS30042Q are available immediately in production quantities and are priced at $0.63 each in 1,000-piece lots.
