The LTC6652 family of precision, low drift, low noise references is fully specified over the temperature range of –40°C to 125°C. High order curvature compensation allows these references to achieve a low drift of less than 5ppm/°C with a predictable temperature characteristic and an output voltage accuracy of ±0.05%. The performance over temperature should appeal to automotive, high performance industrial and other high temperature applications.The LTC6652 voltage references can be powered from supply voltages up to 13.2V. They boast low noise, excellent load regulation, source and sink capability and exceptional line rejection, making them a superior choice for demanding precision applications. A shutdown mode allows power consumption to be reduced when the reference is not needed. The optional output capacitor can be left off when space constraints are critical.The LTC6652 references are offered in an 8-lead MSOP package and an 8-lead LS8 package. The LS8 is a 5mm × 5mm surface mount hermetic package that provides outstanding stability.Applications Automotive Control and Monitoring High Temperature Industrial High Resolution Data Acquisition Systems Instrumentation and Process Control Precision Regulators Medical Equipment

The MAX15004/MAX15005 high-performance, current-mode PWM controllers operate at an automotive input voltage range from 4.5V to 40V (load dump). The input voltage can go lower than 4.5V after startup if IN is bootstrapped to a boosted output voltage. The controllers integrate all the building blocks necessary for implementing fixed-frequency isolated/nonisolated power supplies. The general-purpose boost, flyback, forward, and SEPIC converters can be designed with ease around the MAX15004/MAX15005.The current-mode control architecture offers excellent line-transient response and cycle-by-cycle current limit while simplifying the frequency compensation. Programmable slope compensation simplifies the design further. A fast 60ns current-limit response time, low 300mV current-limit threshold makes the controllers suitable for high-efficiency, high-frequency DC-DC converters. The devices include an internal error amplifier and 1% accurate reference to facilitate the primary-side regulated, single-ended flyback converter or nonisolated converters.An external resistor and capacitor network programs the switching frequency from 15kHz to 500kHz (1MHz for the MAX15005). The MAX15004A/MAX15005 provide a SYNC input for synchronization to an external clock. The maximum FET-driver duty cycle for the MAX15004A/B/C/D is 50%. The maximum duty cycle can be set on the MAX15005A/B/C/D by selecting the right combination of RT and CT.The input undervoltage lockout (ON/active-low OFF) programs the input-supply startup voltage and can be used to shutdown the converter to reduce the total shutdown current down to 10µA. Protection features include cycle-by-cycle and hiccup current limit, output overvoltage protection, and thermal shutdown.The MAX15004/MAX15005 are available in space-saving 16-pin TSSOP and thermally enhanced 16-pin TSSOP-EP packages.
