The AP6714 boost and the AP6015 buck converters have 2.2- and 1.2-MHz maximum switching frequencies, respectively. Claiming 94% efficiency, the synchronous dc/dc converters provides 150-mA quiescent ...

Finally, an inverting buck-boost converter places additional voltage and current stresses on the power devices compared with a four-switch buck-boost circuit, reducing relative efficiency. But the ...

Asynchronous boost converters often struggle to provide high output current without experiencing substantial power losses and heating of the catch diode under normal operation.

A boost converter can have as few as four basic components — a power semiconductor MOSFET switch (M), a diode (D), an inductor, or “boost choke,” (L) and a bulk storage capacitor (C) — but ...

Undervoltage lockout, thermal shutdown, peak current limit, negative current limit, and output short-circuit protection functions are also included. The AP72250 is supplied in a WLCSP-12 package ...

The AP72250 supports a 900kHz switching frequency with a 20µA quiescent current (IQ) and covers a wide input voltage range between 0.6V and 5.5V, with a minimum 1V input start-up, and has a 1.7V to ...

Diodes has introduced a boost converter that can supply constant voltage or constant current to drive backlights, with a dimming ratio of 100:1. Called AL3353, it has an input voltage of 9V to 40V – ...

The MT3608 is a popular boost converter, able to easily step up DC voltages in useful ranges, at an incredibly low cost. Modules can be sourced from eBay for less than $2, built on a PCB, ready to go.

Date Announced: 13 Mar 2007 Linear Technology has announced the LT3494/A low noise boost converters with integrated power switches, Schottky diodes and output disconnect circuitry. The LT3494 uses a ...

Diodes Incorporated (Diodes) (Nasdaq: DIOD) has introduced a high-efficiency synchronous boost converter. The DIODES™ AP72250 is targeted at step-up conversion in consumer and industrial ...
