150-mA synchronous DC/DC regulators optimize light-load efficiency for factory automation and automotive applications

Texas Instruments (TI) (NASDAQ: TXN) introduced two 65-V, 150-mA synchronous DC/DC buck converters with what the company said is the industry’s lowest 10.5-uA quiescent current (IQ) for powering factory automation and automotive sensor applications requiring high efficiency.

The industrial-grade LM5165 and automotive-grade LM5165-Q1 micro-power step-down regulators feature a wide input voltage (VIN) range and dual control modes for optimizing efficiency and printed circuit board (PCB) area. By using the regulators together with TI’s WEBENCH® Power Design tool, engineers can get their factory and process automation designs to market faster.

8µA Quiescent Current Surge Stopper

Linear Technology Corporation introduced the LTC4380, an ultralow quiescent current (IQ) surge stopper, providing compact overvoltage and overcurrent protection for always-on 4V to 72V electronics in automotive, industrial and avionic systems.

The LTC4380 replaces traditional shunt circuits composed of bulky inductors, capacitors, transient voltage suppressors (TVS), and fuses with a simple IC and series N-channel MOSFET solution, saving board space and enabling continuous operation through transient voltage or current surges. The LTC4380 protects downstream electronics from input overvoltage up to the MOSFET rating, while also protecting the power supply from output overload. Device current consumption is a mere 8µA in normal operation and 6µA in shutdown mode, prolonging battery run and standby time. The low current allows a large filtering resistor to the device supply pin, enabling operation through automotive cold crank and overvoltage transients above 100V.

Allegro Introduces Wide Input Voltage Buck Regulators

allegro 5-2-16 A8586-A8587-Product-ImageSwitching Regulators with Adjustable Frequency

Allegro MicroSystems, LLC introduced two new adjustable high-frequency DC-DC step-down switching regulators with an integrated high-side power MOSFET ideal for power supply requirements of the latest infotainment systems.

Allegro’s A8586 provides up to 3.5 A output current, while the A8587 has output current of up to 2.0 A. Both devices are automotive, AEC-Q100 qualified and incorporate current-mode control for fast transient response. The wide input range of 3.8 to 36 V makes both devices suitable for a wide range of step-down applications, including those in an automotive input environment. Battery-driven “keepalive” applications benefit from the low 30 μA operational quiescent current. Both devices are designed to robustly handle a load dump condition with 40 V maximum rating as well as idle-stop and cold crank conditions with 3 V UVLO rating.
