36V Synchronous Micro Buck Regulator is Industry’s Smallest IC with Tiny Solution Size

The 36V, 300mA MAX15062* buck regulator in a 2mm x 2mm TDFN package is ideal for space-constrained applications. Built from the ground up for industrial, medical, and mobile applications that operate on 24V nominal rail, this regulator can supply low-power ASICs, FPGAs, and CPLDs. Integrated switching MOSFETs, synchronous rectification, and internal compensation reduce external components to less than half the closest competing device.

CONTROL

Maxim’s 1-Wire bus is a simple signaling scheme that performs half-duplex bidirectional communications between a host/master controller and one or more 1-Wire slaves sharing a common data line. Both power and data communication for slave devices are transmitted over this single 1-Wire line.

Users can evaluate a variety of 1-Wire memory, digital, analog, and mixed-signal functionality on CoolRunner II-based designs. The on-board CPLD emulates a 1-Wire translator and controls communication between the system host and one or more 1-Wire slaves. The on-board Maxim DS28E01-100 1-Wire secure memory uses an elegant challenge-and-response authentication sequence to differentiate between authorized and cloned environments. This determination either sets the system to normal operation or disables the design, thereby protecting the design investment from copying and cloning. Additional 1-Wire solutions can be evaluated using on-board PMOD connectors.

Benefits• Minimal overhead for adding functionality • Simplified, yet elegant interconnect• Offers wide range of memory, security,

digital, and mixed-signal functionality

Applications• IP and design protection• Environmental monitoring and control• Battery management• I/O expanders for relay and LED control

50mA, 10µA IQ Automotive LDOs are Best Choice for Always-On Applications

www.maxim-ic.com/MAX15006

The MAX15006/MAX15007 LDO regulators integrate a high-voltage, p-channel MOS pass transistor, provide low 10µA quiescent current, and load-dropout operation from 4V to 40V. Both are available in a small, 3mm x 3mm TDFN package with exposed pad and use only a 2.2µF output capacitor to enable a small-solutions size capable of operating up to +125°C.

Features and Benefits• 10μA quiescent current at no load for better system

efficiency• 46% lower junction-to-case thermal resistance

(θJC = 8.5°C/W) to run 50mA load at high temperatures• 40% smaller package (3mm x 3mm) to reduce board space
