+Vin -Vin On/Off +Vo Adj. -Vo Block Diagram More Power High Power Density Vout Adj.Low Noise Remote on/offWide Range 3:1 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. y Standby Current 100uA only y Overload Protection y Step-down Switching Regulator y Temperature Performance -25] to +70] y Low Output Noise y Remote On/Off Control y Low Cost y MTBF > 1,500,000 Hours y Output Current up to 2A y Efficiency up To 93% Key Features 10W, Step-Down, Single Output DC/DC Converters IDS100 Series REV:0 2005/04MINMAX1

Peak-to-Peak Output Noise Measurement Test Use a Cout 4.7uF ceramic capacitor. 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. Design & Feature Considerations 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 -100 uA. The maximum allowable leakage current of the switch at on/off terminal (3.0 to 5.0V) is 50uA. Overcurrent Protection To provide protection in a fault (output overload) condition, the unit is equipped with internal current limiting circuitry and can endure current limiting for an unlimited duration. At the point of current-limit inception, the unit shifts from voltage control to current control. The unit operates normally once the output current is brought back into its specified range. 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 22uF capacitors at the output. 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 < 1.0[ at 100 KHz) capacitor of a 100uF for the 5V input devices and a 33uF for the 12V and 24V devices. 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: 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°C. The derating curves are determined from measurements obtained in an experimental apparatus.
