control their high-power supply systems,” said Ed Lam, senior director of IDT’s Power Business Unit. “The ZSPM1363 is a high- performance digital power controller that delivers design flexibility to reduce development cost and time to market. And because we developed it using automotive design methodology, the chip is rugged and highly reliable, with operating temperatures up to 125°C.” The ZSPM1363 features simple resistor-based compensation adjustment after programming if load condition changes; there’s no need to reprogram the chip. And its multi-programmable compensation architecture achieves fast transient response while providing low ripple, steady state performance.

operating conditions, and tolerance of electrostatic discharge (ESD) up to 4kV (HBM1). The TSB572 and TSB611 single op amps are the first devices produced using ST’s new 40V-ready BiCMOS2 semiconductor process. This technology delivers superior GBW/Icc3 efficiency resulting in about five times lower supply current in relation to performance, compared with standard op amps. In addition, low input-offset voltages with temperature drift below 6µV/°C simplify system design, eliminate any need for trimming or calibration, and ensure consistent performance over the specified temperature range -40°C to 125°C. The TSB572, with rail-to-rail inputs and output, has 2.5MHz gain- bandwidth (GBW) and 1.5mV maximum input-offset voltage. The op amp is stable with capacitive loads and highly resistant to phase reversal. Its broad supply-voltage range, from 4.0V to 36V, allows reliance on specified parameters with a wide variety of power supplies. The TSB611 has 560kHz GBW and can operate from a supply voltage as low as 2.7V. It is a unity-gain- stable device, and has extremely low input-offset voltage of 1mV as well as frugal operating current of 125µA (max.) at 36V. Compact package options make ST’s new op amps ideal for use where space is tight, such as in automotive audio systems and Electronic Control Units (ECUs). The TSB572 is in mass production now in 3mm x 3mm DFN or Mini- SO8, priced from $0.80. The TSB611 in SOT23-5 is also in mass production, priced from $0.55 for orders of 1000 pieces.
