The SRBH-06H1A1 is part of the low-cost non-isolated DC-DC
power converter series providing up to 6 A output current.
The output is closely regulated and the efficiency of 3.3 VDC output
is typically 89% at full load.
Typical features include remote on/off, input under-voltage lockout,
over current protection and short circuit protection.

Equations for calculating the trim resistor (in kΩ) given the desired adjusted voltage (Vadj) and the nominal output voltage of the
converter (Vnom = 3.3 V) are shown below. The Trim Down resistor should be connected between the Trim pin and Vout. The Trim
Up resistor should be connected between the Trim pin and Ground. Only one of the resistors should be used for any given
application.

The SRBH-06H1A1 modules are designed to be compatible with reflow soldering process. The suggested Pb-free solder paste is
Sn/Ag/Cu(SAC). The recommended reflow profile using Sn/Ag/Cu solder is shown in the following. Recommended reflow peak
temperature is 245°C while the part can withstand peak temperature of 260°C maximum for 10seconds. This profile should be
used only as a guideline. Many other factors influence the success of SMT reflow soldering. Since your production environment
may differ, please thoroughly review these guidelines with your process engineers.
Figure 15. Soldering information
The SRBH-06H1A1 modules have a MSL rating of 3.
The SRBH-06H1A1 modules are designed to be compatible with J-STD-033 Rev:A (Handling, Packing, Shipping and Use of
Moisture /Reflow Sensitive surface Mount devices). Moisture barrier bags (MBB) with desiccant are applied. The recommended
storage environment and handling procedure is detailed in J-STD-033.
This component has been designed, handled, and packaged ready for Pb-free reflow soldering. If the assembly shop follows J-
STD-033 guidelines, no pre-bake of this component is required before being reflowed to a PCB. Our packaging tray can only
withstand temperature of 70°C max.
