In this article, we’ll explain how an inverter or emergency bulb operates. An inverter bulb is an emergency LED bulb. However, the term is confusing because there’s no conversion process (from dc to ac or vice versa) in the circuits where these bulbs are applied. The technology lets the bulbs automatically light during a power…

A major advantage of a switching regulator is that it can boost a lower voltage into a higher one. This type of regulator is also known as a boost or step-up converter. A boost converter is used to step up an input voltage to a higher level as required by a load. This capability is…

Diodes Incorporated has introduced a high-efficiency synchronous boost converter. The DIODES AP72250 is targeted at step-up conversion in consumer and industrial applications where small form factors are a priority. These include battery-powered devices, USB power-supply units, power banks, supercapacitor charging equipment, and metering systems. The AP72250 supports a 900kHz switching frequency with a 20µA quiescent…

Texas Instruments (TI) introduced a new bidirectional buck/boost converter with an ultra-low quiescent current (IQ) of 60 nA, which is one-third the IQ of competing boost converters. The TPS61094 buck/boost converter integrates a buck mode for supercapacitor charging while providing ultra-low IQ, enabling engineers to extend battery life by as much as 20 percent when compared…

Diodes Incorporated is introducing the PAM8965 class-D stereo, audio power amplifier with an integrated synchronous boost converter. This high-efficiency device is targeted for use in AI-enabled speaker systems and portable musical instruments where elevated output power, extended battery life, and compact construction are all key requirements. Running off a 2.8 to 8.5V supply, the PAM8965…
