Texas Instruments TI LMZ120xx SIMPLE SWITCHER Power Modules

Texas Instruments LMZ120xx SIMPLE SWITCHER® Power Modules provide easy-to-use step-down DC-DC solutions with exceptional power conversion efficiency, output voltage accuracy, line and load regulation. LMZ12001 / LMZ12002 / LMZ12003 SIMPLE SWITCHER® Power Modules can accept an input voltage rail between 4.5V and 20V and deliver an adjustable, highly accurate output voltage as low are 0.8V. These TI power modules have either 1A (LMZ12001), 2A (LMZ12002), or 3A (LMZ12003) output current and offer efficiency of up to 92%. The LMZ12001, LMZ12002, and LMZ12003 have a -40 to +125°C junction temperature range and provide fast transient response for FPGAs and ASICs. These TI devices are ideal for use in point of load conversions from 5V and 12V input rail, time critical, space-constrained high thermal requirement, and negative output voltage applications.
