PRODUCTION DATA.
The TPSM84203, TPSM84205, and TPSM84212 devices are 28 V input, 1.5 A, synchronous step down converters with PWM, MOSFETs, inductor, and control circuitry integrated into a TO-220 footprint package. The device integration enables small designs, while improving efficiency over a traditional linear regulator design. The TPSM842xx family provides fixed output voltages of 3.3 V, 5.0 V and 12.0 V. The fixed 400 kHz (typ) switching frequency allows small size and low output voltage ripple. Under light load conditions, these devices are designed to operate in high-efficiency pulse-skipping mode. These devices provide accurate voltage regulation for a variety of loads by using a precision internal voltage reference. These devices have been designed to safely start up into a pre-biased output voltage. Thermal shutdown and current limit features protect the device during an overload condition. The 3-pin, TO-220 footprint package offers improved performance over traditional linear regulators packaged in the standard footprint.
