Texas Instruments has introduced a synchronous 50mA, 60V SWIFT step-down regulator in a solution size of 125mm2. The TPS54062 integrates both the high-side and low-side power MOSFETs, providing power conversion and transient protection to noise-sensitive industrial automation and sensor control, smart metre, telecomms, computing and consumer designs. The converter operates from -40 to +150°C and provides 90% efficiency at 24VIN, 5VOUT at 150kHz. It can be synchronised to a clock via fixed frequency. The converter also operates at 89µA with a shutdown current of 1.7µA and has switching frequency range over 100 to 400kHz.
The converter can withstand transients up to 65V, while maintaining high efficiency across the load, claims the company. For high voltage transient protection at 50mA, the company recently introduced its TPS7A4001 50mA, 100V LDO (low-dropout regulator), which is claimed to achieve a fast settling time of less than 500ns for a 50V transient event.
The TPS54062 also supports many embedded processor applications, including Stellaris ARM Cortex-M microcontrollers, C5000 power DSPs and power MSP430 16bit microcontroller-based applications, such as smart metre, building automation and security systems. The converter is available in an 8pin, 3x5mm MSOP PowerPad package.
