The module will turn on during the ctrl pin left open or high impedance between ctrl pin and -Vin pin. The module will turn off if the control pin is applied with a current of 4~8mA. DC-DC OFF DC-DC ON +Input +Input 1K Ctrl 6mA current Source 1K 6mA current Source Ctrl -Input -Input In off condition the input current is app. 1mA max. Positive Logic: Negative Logic: Output over current protection When excessive output currents occur in the system, circuit protection is required on all converters. Normally, overload current is maintained at approximately 115~175% percent of rated current. The TMR converters have a fold-back over current protection. Fold back current protection reduces the load current during over current condition. The figure below shows a typical curve. Since the over current protection is a fold-back characteristic the highest power dissipation occurs at point S. During start-up this product provides less output current, hence the output rises slower, or the power supply may not start up at all if the load current during start up is larger than the fold back current. Vout ● S (Iout, max, Pi, max) ● Iocp Pi (Input Power) Short Circuitry Protection Continuous, hiccup and auto-recovery mode. During short circuit, converter will shut down and will switch on again to detect if the short circuit is still present or not. The average current during this condition will be very low and the device will be safe in short circuit condition. Due to that is the TMR converters indefinite short circuit protected.

To assure the solder-ability, modules should be kept in their original shipping containers to provide adequate protection. Also, the storage environment shall be well controlled to protect any oxidation. Cleaning process In aqueous cleaning, it is preferred to have an in-line cleaner system consisting of several cleaning stages (pre-wash, wash, rinse, final rinse, and drying). Deionize (DI) water is recommend for aqueous cleaning; the minimum resistive level is 1M-cm. Tap-water quality varies per region in terms of hardness, chloride, and solid contents; therefore, the use of tap water is not recommended for aqueous cleaning. Drying The drying section of the cleaner system should be equipped with blowers capable of generating 1000cfm -1500cfm of air so that the amount of rinse water left to be dried off with heat is minimal. Handheld air guns are not recommended due the variability and consistency of the operation. Note: after post-wash, the marking (date code) of converter may fall off. These only impacts the appearance and do not affect the operation of the module.

Highly inductive source impedance can affect the stability of the power module. Input external L-C filter is recommended to minimize input reflected ripple current. The capacitor should be equipped as close as possible to the input terminals of the power module for lower impedance.

www.tracopower.com Date: October 9th, 2007 / Rev.: 1.4 / Page 20 / 23 Application Note 2W, Single and Dual Output Thermal Consideration The power module operates in a variety of thermal environments. However, sufficient cooling should be provided to help ensure reliable operation of the unit. Heat is removed by conduction, convection, and radiation to the surrounding Environment. Proper cooling can be verified by measuring the point as shown in the figure below. The temperature at this location should not exceed 100°C. During performance, adequate cooling must be provided to maintain the test point temperature at or below 100°C. Although the maximum point Temperature of the power modules is 100°C, you can limit the case temperature to a lower value for high reliability.

The input to output 9 resistance is greater than 10 ohms. Nevertheless, if the system using the TMR converter needs to get safety agency approval, certain rules must be followed in the design of the system. In particular, all of the creepage and clearance requirements of the end-use safety requirement must be observed. These documents include UL60950-1, EN60950-1 and CSA 22.2-60950, although specific applications may have other or additional requirements. Fusing Consideration Caution: The TMR converter is not internally fused. An input line fuse must always be used. This encapsulated power module can be used in a wide variety of applications, ranging from simple stand-alone operation to an integrated part of a sophisticated power architecture. To maximum flexibility, internal fusing is not included; however, to achieve maximum safety and system protection, always use an input line fuse. The safety agencies require a slow-blow fuse with maximum rating of 6.3 A. Based on the information provided in this data sheet on inrush energy and maximum dc input current, the same type of fuse with lower rating can be used. Minimum Load Requirement No minimum load required. MTBF and Reliability The MTBF of TMR series has been calculated according to: 1. MIL-HDBK-217F under the following conditions: Nominal Input Voltage and GB Iout = Iout max TA = +25°C 6 The resulting figure for MTBF is 2.399× 10 hours. 2. Bell-core TR-NWT-000332 Case I: 50% stress, Operating Temperature at 40 ℃ (Ground fixed and controlled environment) 6 The resulting figure for MTBF is 5.107× 10 hours.
