TI introduces 52-V boost controller for industrial and battery-powered systems

TI’s new TPS40210 non-synchronous DC/DC controller with current mode control supports design configurations that require a grounded source N-channel FET, including boost, flyback and SEPIC topologies. The integrated device provides programmable soft start and several over-current protection features, including a current feedback threshold mechanism in the control loop.

Low-noise 20-V LDOs with ultra-fast transient response TI also introduced the TPS7A4501 and TL1963A LDOs that support input voltages up to 20 V and generate up to 1.5A output current with very low output noise. The LDOs are aimed at applications where low-voltage operation and good transient response are important, such as low-voltage logic and RF power supply applications.

The TPS7A4501 LDO is capable of dropout voltage down to 300 mV, and provides low noise (35 uVrms at 10 Hz to 100 kHz) and an operating quiescent current at 1mA. The TPS7A4501 has an adjustable input voltage of 1.21V to 20V. The TL1963A is similar to the TPS7A4501, but provide a low dropout voltage of 340 mV with a 1.5A output current.
