Bidirectional Switches from Diodes Incorporated Protect 1-Cell and 2-Cell Lithium Batteries During Charging
Plano, Texas - July 9th, 2015 - The DMN2014LHAB and DMN2011UFX dual N-channel enhancement mode MOSFETs introduced by Diodes Incorporated provide a compact, bi-directional low-loss switch for battery-charging circuits. End-markets include chargers for portable devices such as smartphones, tablets, cameras and media players, which use 1-cell and 2-cell lithium batteries.
Plano, Texas - Aimed at increasing the power density of DC-DC converters, the DMC1028UFDB complementary MOSFET pair introduced by Diodes Incorporated integrates an N-channel MOSFET and a P-channel MOSFET in a single DFN2020 package. The design is customized for point-of-load (POL) converters that step down from 3.3V to 1V for core voltage supply to ASICs. Target applications are Ethernet network controllers and processors used in such equipment as routers, network interface controllers (NICs), switches, digital subscriber line (DSL) adaptors, servers, and set-top boxes (STBs).
Plano, Texas - Aimed at smartphones operating from a single-cell lithium-ion battery, the PAM8905 from Diodes Incorporated is a 1.9W class-D audio amplifier designed for audio systems that need to deliver a high sound pressure level (SPL) output from a low supply voltage. It achieves this with a built-in boost converter that generates the voltage rail for the output stage while using a battery-tracking automatic gain control (AGC) to adjust the gain and limit battery current when the battery voltage is low, thus prolonging battery life.
