Dual, Quick-PWM Step-Down Controller Provides a Complete Solution for Notebook Power Supplies
Maxim Integrated Products introduces the MAX17031, a dual, Quick-PWM step-down controller with synchronous rectification specifically intended for generating 5V/3.3V supplies in battery-powered systems. This device integrates a 100mA linear regulator that generates the 5V bias needed for power-up or other lower power, always-on suspend supplies. The controller also includes a low-current (5mA), always-enabled linear regulator to power the real-ti...
Reverse-battery and overvoltage protection controllers provide ideal-diode characteristics
Maxim introduced the MAX16914/MAX16915 overvoltage-protection controllers for automotive and industrial systems that must tolerate high-voltage transient and fault conditions. These devices employ a unique architecture that senses the input and output voltages of two back-to-back p-channel MOSFETs to provide overvoltage protection with ideal-diode characteristics. When forward biased, the two pFETs have a voltage drop that is much lower than a t...
MAX8895: Industry's first battery charger with automatic USB enumeration
Maxim introduced the MAX8895, a linear battery charger for Bluetooth(R) headsets and portable devices that is compatible with the USB Battery Charging Specification, Revision 1.1. The MAX8895 is uniquely equipped with automatic adapter detection for distinguishing between USB devices, USB chargers, and dedicated chargers. It also integrates a USB enumeration function that automatically negotiates with the USB host to optimize charging current wit...
MAX15040: 4A switching regulator simplifies designs and improves reliability
Maxim introduced the MAX15040, a low-voltage (2.4V to 3.6V), synchronous switching regulator in a 2mm x 2mm wafer-level package (WLP). This miniature step-down regulator integrates MOSFETs to simplify design, minimize EMI, improve reliability, and save board space.
