Description
The HWD15 series provide on-board conversion of standard telecom and datacom input voltages into two
isolated low-voltage outputs. These products offer a unique combination of wide input range, low profile, and
high current capability. High efficiency and advanced thermal management enable these half-brick products to
deliver full rated power at 55°C ambient temperature, with 200LFM airflow, without the addition of heatsinks.

Feature Descriptions
Output Overvoltage Clamp
The output overvoltage clamp consists of a separate control loop, independent of the primary control loop. This
control loop has a higher voltage setpoint than the primary loop. In a fault condition the converter goes into
“Hiccup Mode”, and the output overvoltage clamp ensures that the output voltage does not exceed
Vo,clamp,max. This secondary control loop provides a redundant voltage-control that reduces the risk of output
overvoltage.

Output Current Protection
To provide protection in an output overload or short circuit condition, the converter is equipped with current
limiting circuitry and can endure the fault condition for an unlimited duration. At the point of current-limit
inception, the converter goes into “Hiccup Mode”, causing the output current to be limited both in peak and
duration. The converter operates normally once the output current is brought back into its specified range.
Enable
Two enable options are available. Positive Logic Enable and Negative Logic Enable. Positive Logic Enable turns
the converter on during a logic-high voltage on the enable pin, and off during a logic-low. Negative Logic Enable
turns the converter of during a logic-high and on during a logic-low.
Output Voltage Adjustment
Output voltage adjustment is accomplished by connecting an external resistor between the Trim Pin and either
the +Vo1 or –Vo1 Pins.
With an external resistor between the Trim Pin and +Vo1 Pin (Radj-down) the output voltage set point (Vo,adj)
decreases. The following equation determines the required external resistor value to obtain an adjusted output
voltage:

Where Radj-down is the resistance value and A, B, and D are defined in Table 7.

increases. The following equation determines the required external resistor value to obtain an adjusted output

Thermal Considerations
The power converter operates in a variety of thermal environments: however, sufficient cooling should be
provided to help ensure reliable operation of the converter. Heat-dissipating components are thermally coupled
to the case. Heat is removed by conduction, convection, and radiation to the surrounding environment. Proper
cooling can be verified by measuring the case temperature.
Heat Transfer Characteristics
Increasing airflow over the converter enhances the heat transfer via convection. Figure 3 shows the maximum
power that can be dissipated by the converter without exceeding the maximum case temperature versus local
ambient temperature (TA) for natural convection through 400 ft/min.
Systems in which these converters are used generate airflow rates of 50 ft/min due to other heat dissipating
components in the system. Therefore, the natural convection condition represents airflow rates of approximately
50 ft/min. Use of Figure 3 is shown in the following example.
Example
What is the minimum airflow required for the device operating at 24 V, an output power of 60 W, and maximum
ambient temperature of 60 ºC.
Solution:
Given: Vi = 24 V, Po = 60 W, TA = 60 ºC.
Determine PD (Figure 4): PD = 13 W.
Determine airflow (Figure 3): v = 200 ft/min
