Fig. 1. Non-inverting buck-boost with integrated MOSFETs. There are two fundamental methods to control the bridge MOSFETs in a non-inverting, buck-boost converter that uses a fixed-frequency PWM. The ...

Containing independent boost and buck controllers, the LTC7813 from Linear Technology operates from an input voltage of 4.5 V to 60 V. The synchronous DC/DC controller can regulate two separate ...

According to austriamicrosystems, this low voltage DC-DC IC offers power-ok signalling. The AS1337 implements a boost architecture with efficiencies said to be up to 97%, while the converter is ...

4. The LTC3119 buck-boost converter IC is housed in a thermally enhanced, 28-lead, 4- × 5-mm QFN or TSSOP package. Capacitor Selection. A low-ESR (equivalent series resistance) output capacitor ...

A synchronous buck-boost converter IC from Linear Technology builds on the success of the company’s LTC3440 by extending that device’s input voltage range and by making burst-mode operation ...

Super cap back-up buck-boost converter idles at 60nA Texas Instruments has introduced an IC to mediate between a power rail, a load and a back-up supercapacitor. All the time sufficient voltage is ...

A reference design kit, RDK-707Q, is available for designers wishing to evaluate the LinkSwitch-TN2Q IC family. Devices are priced starting at $1.33 for LNK3209GQ-TL in 10,000-unit quantities.

The module under the knife is a popular buck-boost converter with a wide input range, 0-32 VDC output at up to 5 amps, and a fancy controller with an LCD display.

Texas Instruments (TI) has introduced a bidirectional buck/boost converter with an ultra-low quiescent current (IQ) of 60 nA. The TPS61094 integrates a buck mode for supercapacitor charging while ...
