Step Up/Down Converter Features Seamless Transition Switching

The MAX8625A, a single-inductor, H-bridge step-up/-down dc/dc converter employs the company's patented, seamless transition H-bridge topology that utilizes three operating phases during each switching cycle to achieve glitch-free buck/boost transitions. The device minimizes output-ripple variations in transitions and provides an efficiency up to 92% over a 2.5V to 5.5V input-voltage range. Additional features include a 37 mA quiescent current in skip mode, fixed 3.3V or adjustable 1.25V to 4V output voltage, internal compensation, soft-start, and TrueShutdown circuitry, which disconnects the output from the input when the IC is disabled. Available in a 14-pin TDFN package measuring 3 mm x 3 mm, pricing starts at $2.45 each/1,000. MAXIM INTEGRATED PRODUCTS, Sunnyvale, CA. (800) 998-8800.
