TOS

DC/DC Converters TOS Series, Point-of-Load (POL) Converter Features ◆ Small Size, low Profile ◆ SMT package or SIP version ◆ Cost-efficient open Frame Design ◆ Wide Input Voltage Ranges ◆ Output Voltages trim from 0.75VDC to 5.0VDC compliant RoHS ◆ ◆ ◆ ◆ ◆ ◆ ◆ Delivers up to 16A with minimal derating Ultra high Efficiency to 96% Fast Transient Response Remote On/Off Control Wide Temperature Range( -40°C to 85°C) SMT Package fully DOSA compatible Lead free Design – RoHS compliant The TOS series is a range of high performance non-isolated dc-dc converters With very high efficiency that can supply up to 16A of output current. These modules provide precisely regulated output voltages which can be set via an external resistor to a value from 0.75 VDC to 5.0VDC. These converters work over a wide input voltage range of 2.4 to 5.5VDC or 8.3 to 14.0VDC.Further features include remote On/Off, under voltage lockout, over temperature and over current protection. These products have an open-frame construction with very small footprint and are available in an industry standard SIP or in a SMT package. The TOS series is fully RoHS compliant and can withstand industry standard handling, cleaning and the high temperatures of lead-free reflow solder processes.
