40V amplifier significantly improves system performance

Analog Devices has introduced the industry’s fastest operational amplifier for driving heavy loads at high voltage and high output current, including piezoelectric transducers, PIN diodes, laser diodes, power FETs, coils and CCDs. The 40-V ADA4870 amplifier delivers over 1A of output current at more than twice the slew rate (2500 V/s) of competing high output-power amplifiers, enabling applications including higher accuracy, high-intensity focused ultrasound (HIFU) for medical equipment and higher efficiency envelope tracking solutions in small-cell base stations and military radios.

Buck controller optimises notebook performance

Buck controller optimises notebook performance
The AP3591 single-phase, synchronous step-down controller from Diodes Incorporated is designed to provide enhanced transient response and output accuracy for low-voltage regulation in notebooks and all-in-one PCs. Operating at a resistor-programmed fixed frequency between 100kHz to 700kHz, the device’s adaptive constant-on-time control algorithm is capable of handling very wide input/output voltage ratios and helps reduce external component counts.

45V input 200mA LDO offers active output discharge

45V input 200mA LDO offers active output discharge
Linear Technology announces the LT3063, a high voltage, low noise, low dropout voltage linear regulator with active output discharge. The IC delivers up to 200mA of continuous output current with a 300mV dropout voltage at full load. The LT3063 includes an internal NMOS pull-down that discharges the output voltage if either the SHDN pin is driven low or the input voltage is turned off.
