DESCRIPTIONDual Synchronous, 800mA, 2.25MHz Step-Down DC/DC RegulatorThe LTC3407-2 is a dual, constant-frequency, synchro-nous step down DC/DC converter. Intended for low power applications, it operates from 2.5V to 5.5V input voltage range and has a constant 2.25MHz switching frequency, allowing the use of tiny, low cost capacitors and inductors with a pro le 1.2mm. Each output voltage is adjustable from 0.6V to 5V. Internal synchronous 0.35, 1.2A power switches provide high ef ciency without t

The AAT1108 series provides an integrated two-channel pulse-width-modulation (PWM) solution for the power supply of DC-DC system, this device offers the systems engineer the flexibility to tailor the power supply circuitry to a specific application. Each channel contains its own error amplifier, PWM comparator, dead"time control and output driver. The under-voltage protection, oscillator, short circuit protection and voltage reference circuit are common for the two channels.

The SP6128A is a fixed frequency, voltage mode, synchronous PWM controller designed to work from a single 5V or 3.3V input supply, providing excellent AC and DC regulation for high efficiency power conversion. Requiring only few external components, the SP6128A packaged in an 14-pin TSSOP, is especially suited for low voltage applications where cost, small size and high efficiency are critical. The operating frequency is internally set to 300kHz, allowing small inductor values and minimizing PC

M/A-COM's MABAES0022 is a 9:1 RF transmission line transformer in a low cost, surface mount package. Impedence 75 Ohms to 337 Ohms.

The DC/DC module is a high efficiency DC/DC not insulated switch mode constant voltage generator. Designed for industrial application where low voltages are required from main.

The LM2717-ADJ is composed of two PWM DC/DC buck (step-down) converters. Both converters are used to generate an adjustable output voltage as low as 1.267V. Both also feature low RDSON (0.16.) internal switches for maximum efficiency.

The AIC 1633 is a high efficiency step up DC/DC converter. Only four external components are required to deliver a fixed voltage of 3V, 3.3V, or 5V. The output voltage can be externally set to an arbitrary value below breakdown voltage of the power switch for AIC1633A. Efficiency beyone 83% can be easily achieved at 70mA load with 2.2V to 3V input voltages.
