Demonstration circuit 1367A features the LTM4615EV, a triple output μModule® regulator consisting of two switch-mode outputs and one LDO output. Each LTM4615 DC/DC converter has a separate input and enable pin. The input supply voltage is 2.5V to 5.5V and the demo board provides outputs of 1.8V @ 4A, 1.2V @ 2.5A and 1V @ 1.5A. The LTM4615's maximum load current is 4A for each switch-mode channel and 1.5A for the VLDO™ channel. However the DC1367A is configured with the LDO input supply connected to the VOUT2 whose maximum output current decreases accordingly. Derating is necessary for certain VIN, VOUT and thermal conditions.

Demonstration circuits 1387A-A and A-B are Ultralow Power Boost Converters with Output Disconnect featuring the LT8410 and LT8410-1. Both versions convert a 3V-10V source. The -A version supplies 1.6mA at 3VIN and the -B supplies 0.5mA. Both versions feature a low noise variable off-time and variable peak current control scheme, integrated Schottky diode and output disconnect function, ultralow quiescent current, built-in soft-start and overvoltage protection.

The LTC1436A/LTC1437A are synchronous step-down switching regulator controllers that drive external N-channel power MOSFETs in a phase lockable, fixed frequency architecture. The Adaptive Power? output stage selectively drives two N-channel MOSFETs at frequencies up to 400kHz while reducing switching losses to maintain high efficiencies at low output currents.An auxiliary 0.5A linear regulator using an external PNP pass device provides a low noise, low dropout voltage source. A secondary winding feedback control pin (SFB) guarantees regulation regardless of the load on the main output by forcing continuous operation.An additional comparator is available for use as a lowbattery detector. A power-on reset timer (POR) is included which generates a signal delayed by 65536/fCLK (300ms typically) after the output is within 5% of the regulated output voltage. Internal resistive dividers provide pin selectable output voltages with remote sense capability.The operating current level is user-programmable via an external current sense resistor. Wide input supply range allows operation from 3.5V to 30V (36V maximum).Applications Notebook and Palmtop Computers, PDAs Cellular Telephones and Wireless Modems Portable Instruments Battery-Operated Devices DC Power Distribution Systems
