The LTC6602 is a dual, matched, programmable bandpass or lowpass filter and differential driver. The selectivity of the LTC6602, combined with its phase matching and dynamic range, make it ideal for filtering in RFID systems. With two degree phase matching between channels, the LTC6602 can be used in applications requiring highly matched filters, such as transceiver I and Q channels. Gain programmability, and the fully differential inputs and outputs, simplify implementation in most systems. Both channels of the LTC6602 consist of a programmable lowpass and highpass filter. For bandpass functionality, the lowpass filters are programmed for the upper cutoff frequency. For lowpass functionality, the highpass filters can be bypassed. The filter cutoff frequencies can be set with a guaranteed accuracy of 3% with the use of a single resistor. Alternatively, the filter cutoff frequencies can be controlled with an external clock. The LTC6602 operates on a single 2.7V to 3.6V supply and features a low power shutdown mode.Applications Multiprotocol RFID Readers: EPC-GEN2, ISD and IPX IDEN, PHS, GSM Basestations Repeaters, Radio Links, and Modems Wireless Telemetry JTRS

The LTC3611 is a high efficiency, monolithic synchronous step-down DC/DC converter that can deliver up to 10A output current from a 4.5V to 32V (36V maximum) input supply. It uses a constant on-time valley current mode control architecture to deliver very low duty cycle operation at high frequency with excellent transient response. The operating frequency is selected by an external resistor and is compensated for variations in VIN and VOUT. The LTC3611 can be configured for discontinuous or forced continuous operation at light load. Forced continuous operation reduces noise and RF interference while discontinuous mode provides high efficiency by reducing switching losses at light loads. Fault protection is provided by internal foldback current limiting, an output overvoltage comparator and an optional short-circuit shutdown timer. Soft-start capability for supply sequencing is accomplished using an external timing capacitor. The regulator current limit is user programmable. A power good output voltage monitor indicates when the output is in regulation. The LTC3611 is available in a compact 9mm ? 9mm QFN package.Applications Point of Load Regulation Distributed Power Systems

The LTC3633 is a high efficiency, dual-channel monolithic synchronous buck regulator using a controlled on-time, current mode architecture, with phase lockable switching frequency. The two channels can run 180? out of phase, which relaxes the requirements for input and output capacitance.

The high frequency capability allows the use of small surface mount inductors and capacitors. The unique constant frequency/controlled on-time architecture is ideal for high step-down ratio applications that operate at high frequency while demanding fast transient response. An internal phase lock loop servos the on-time of the internal one-shot timer to match the frequency of the internal clock or an applied external clock.The LTC3633 can select between forced continuous mode and high efficiency Burst Mode operation.Applications Distributed Power Systems Battery Powered Instruments Point of Load Power Supplies

The LTC1645 is a 2-channel Hot Swap? controller that allows a board to be safely inserted and removed from a live backplane. Using external N-channel pass transistors, the supply voltages can be ramped at a programmable rate. Two high side switch drivers control the N-channel gates for supply voltages ranging from 1.2V to 12V. The two channels can be set to ramp up and down separately, or they can be programmed to rise and fall simultaneously, ensuring power supply tracking at the two outputs.Programmable electronic circuit breakers protect against shorts at either output. The RESET output can be used to generate a system reset when a supply voltage falls below a user-programmed voltage. An additional spare comparator is available for monitoring a second supply voltage.The LTC1645 is available in the 8- and 14-pin SO packages.Applications Hot Board Insertion Power Supply Sequencing Electronic Circuit Breaker
