Texas Instruments Incorporated (TI) has introduced its first 2.5-A step-down SWIFT converter to support input voltages up to 60 volts. The new TPS54260 monolithic synchronous switcher with integrated high-side FET provides up to 95-per cent efficiency and low operating current to 12-, 24- and 48-V point-of-load designs and GSM/GPRS modules used in electronic meters (e-meters), fleet management and security systems.
The converter offers a high degree of performance and reliability, including current mode control, which provides fast transient response, simple external compensation and flexible component selection. The device also enters into a low ripple pulse skip mode, which reduces the no load, regulated output supply current down to 138 uA. When disabled, the device draws only 1.3 uA.
The TI SWIFT converters efficiently manage the system power requirements in industrial applications that use TI microcontrollers (MCUs), including C2000 real-time control MCUs and MSP430 ultra-low power MCUs. Other 60-V converters, such as the TPS54160 1.5-A device and TPS54060 0.5-A device, provide lower current and high-efficiency. All three SWIFT converters are pin-compatible for design flexibility.
