IDS100 SERIES DC/DC CONVERTER 10W, Step-Down SIP&DIP Package FEATURES ►Efficiency up To 93% ►Output Current up to 2A ►MTBF > 1,500,000 Hours ►Low Cost ►Remote On/Off Control ►Low Output Noise ►Temperature Performance -25℃ to +85℃ ►Step-down Switching Regulator ►Overload Protection ►Standby Current 100µA only ►3 Years Product Warranty PRODUCT OVERVIEW High efficiency, wide input voltage range and low output noise define Minmax's IDS Series of non-isolated, step-down, switching DC/DC converters. The 3.3V and 5V output devices are respectively up to 93% efficiency. All models are fully line and load regulated and maintain specified accuracy over the impressively wide input voltage ranges of 4.75 to 13.6V for 3.3V output, 6 to 16.5V for 5V output and 16 to 28V for 3.3V and 5V outputs. Output ripple and noise are typically 30mV P-P. The high efficiency of the IDS Series eliminates the need for thermally conductive potting compound. Devices are specified for full-power operation up to ambient temperatures of +70℃ Calculated MTBF (MIL-HDBK-217F) is more than 1.5 million hours. These simple-to-use power converters have no minimum load requirements. They draw 1mA when unloaded and a mere 100uA in the standby mode (On/Off Control turns off). 3.3V models have an output voltage adjustment range from 1.8 to 3.3V and 5V models are adjustable down to 3.0V.

Transient recovery time is measured to within 1% error band for a step change in output load of 50% to 100%. These power converters require a minimum output loading to maintain specified regulation, operation under no-load conditions will not damage these modules; however they may not meet all specifications listed. We recommend to protect the converter by a slow blow fuse in the input supply line. Other input and output voltage may be available, please contact factory. To order the converter with DIP Package, please add suffix D (e.g. IDS101D) to order code. That “natural convection” is about 20LFM but is not equal to still air (0 LFM). Specifications are subject to change without notice.

Scope measurement should be made by using a BNC socket, measurement bandwidth is 0-20 MHz. Position the load between 50 mm and 75 mm from the DC/DC Converter. +Vin +Out Copper Strip Single Output DC / DC Converter -Vin Cout -Out Scope Resistive Load Copper Strip Technical Notes Remote On/Off Positive logic remote on/off turns the module on during a logic high voltage on the remote on/off pin, and off during a logic low. Negative logic remote on/off turns the module off during a logic low and on during a logic high. To turn the power module on and off, the user must supply a switch to control the voltage between the on/off terminal and the -Vin terminal. The switch can be an open collector or equivalent. A logic low is -0.3V to 1.2V. A logic high is 3.0V to 5.0V. The maximum sink current at on/off terminal during a logic low is -100µA. The maximum allowable leakage current of the switch at on/off terminal (3.0 to 5.0V) is 50uA. Output Voltage Trim Connecting the external resistor (Radj) between the Vadj and +Vout pins decreases the output voltage to set the point as defined in the following equation: IDS101 and IDS121 == > Rx=2130Ω Output Voltage range is 1.8-3.3VDC IDS112 and IDS122 == > Rx=3840Ω Output Voltage range is 3.0-5.0VDC + DC Power Source - +Vin +Out -Vin -Out On/Off Vadj Fuse Load Radj Input Source Impedance The power module should be connected to a low ac-impedance input source. Highly inductive source impedances can affect the stability of the power module. In applications where power is supplied over long lines and output loading is high, it may be necessary to use a capacitor at the input to ensure startup. Capacitor mounted close to the power module helps ensure stability of the unit, it is recommended to use a good quality low Equivalent Series Resistance (ESR < 1.0Ω at 100 KHz) capacitor of a 100µF for the 5V input devices and a 33µF for the 12V and 24V devices. + DC Power Source +Vin + +Out DC / DC Converter Load Cin - -Vin -Out Output Ripple Reduction A good quality low ESR capacitor placed as close as practicable across the load will give the best ripple and noise performance. To reduce output ripple, it is recommended to use 22µF capacitors at the output. + +Vin DC Power Source - +Out Single Output DC / DC Converter -Vin Cout Load -Out Thermal Considerations Many conditions affect the thermal performance of the power module, such as orientation, airflow over the module and board spacing. To avoid exceeding the maximum temperature rating of the components inside the power module, the ambient temperature must be kept below 70℃. The derating curves are determined from measurements obtained in an experimental apparatus.
