2 DESCRIPTION of HSA28 Series  Military Grade DC-DC Converters

The operating principle is that the sampling signal of output voltage, coupled by the opto-coupler, works together with the sampling signal of input loop current to regulate the pulse width of the controller. The double close loop control can create constant voltage output and short circuit protection.
Thick film hybrid  integrated techniques provide the HSA28 Series of DC DC converters with reliability levels and optimum miniaturization. The design and manufacturing process of HSA28 Series of converters are in compliance with General Standards of Hybrid Integrated Circuits (MIL-883 DC/DC converters)and detailed standards of manufacturing. Connected to a HFD-CE03 filter, the HSA28 Series of converter can achieve better electromagnetic compatibility (EMC) performance.

Notes to Specifications:
  • The step load transition time should be greater than or equal to 10µs.
  • The step line transition time should be greater than or equal to 10µs.
  • Recovery time is measured from application of the transient to point at which VOUT is within 1% of VOUT at final value.

  • The step load transition time should be greater than or equal to 10µs.
  • The step line transition time should be greater than or equal to 10µs.
  • Recovery time is measured from application of the transient to point at which VOUT is within 1% of VOUT at final value.

Figure 20  Part Numbering Key

Application Notes:

  • The correct power supply is to be ensured that may not cause permanent damage to the device.
  • When the electrical performance is tested, the testing position should be pin of the device.
  • When the device is mounted, the bottom of the device should be closely attached to the circuit board. So as to avoid the damage of the pins, the shockproof should be increased when it is required
  • The pin should not be bending to avoid the glass insulator breaking and case leakage.
  • When the case temperature is at 105℃,  it is suggested that thickness of the thermal sinking plate(copper material) is 3mm, the dimension is greater than 100mm×100mm.
  • When the case temperature is at 125℃,  it is suggested that thickness of the thermal sinking plate is 3mm, the dimension is greater than 120mm×80mm.
