Texas Instruments LMZ236xx SIMPLE SWITCHER Power Modules

Texas Instruments LMZ236xx series SIMPLE SWITCHER® Power Modules for High Output Voltage provide easy-to-use step-down DC-DC solutions. LMZ236xx power modules are available in output currents up to 10A with additional features for powering high current intermediate rails, FPGAs, and noise sensitive applications. LMZ23603 / LMZ23605 / LMZ23608 / LMZ23610 SIMPLE SWITCHER® Power Modules can accept an input voltage rail between 6V and 36V and deliver an adjustable, highly accurate output voltage as low are 0.8V. These TI power modules have either 3A (LMZ23603), 5A (LMZ23605), 8A (LMZ23608), or 10A (LMZ23610) output current and offer efficiency of up to 92%. These power modules have a -40 to +125ºC 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 12V input rail, time critical, space-constrained high thermal requirement, and negative output voltage applications.
