Texas Instruments has introduced a synchronous 50 mA, 60 V SWIFT step-down regulator with high efficiency and low noise performance in a solution size of only 125 mm². The TPS54062 integrates both the high-side and low-side power MOSFETs, providing efficient power conversion and transient protection to noise-sensitive industrial automation and sensor control, smart meter, telecom, computing and consumer designs.
The converter can withstand high-voltage transients up to 65 V, while maintaining high efficiency across the load. For higher-voltage transient protection at 50 mA, TI recently introduced its new TPS7A4001 – a 50 mA, 100 V LDO which achieves a fast settling time of less than 500 nanoseconds for a 50 V transient event.
The TPS54062 offers wide temperature operation (-40°C to 150°C) and efficiency up to 90% (24 Vin, 5 Vout at 150 kHz). It uses 89 μA operating current with a shutdown current of only 1,7 μA.
