General Description
TOS xx-xxSM (SMD package) and TOS xx-xxSIL (SIP package) are non-isolated DC/DC Point-of-Load converters that can
deliver up to 6A (TOS 06-xxyyy), 10A (TOS 10-xxyyy) or 16A (TOS 16-xxyyy) of output current with an efficiency of up to 94%
at 3.3V output voltage. These modules provide precisely regulated output voltage adjustable via external resistor between
0.75Vdc and 3.3Vdc (TOS xx-05yyy) or 0.75Vdc and 5.0Vdc (TOS xx-12yyy) over a wide input voltage range between Vin =
2.4 and 5.5Vdc (TOS xx-05yyy) or 8.3Vdc and 14.0Vdc (TOS xx-12yyy). Their open frame construction and small footprint
enable designers to develop cost- and space-efficient solutions.

Thermal Consideration of TOS 06-05yyy
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, convention, and
radiation to the surrounding Environment. Proper cooling can be verified by measuring the point as the
figure below. The temperature at this location should not exceed 125°C (TOS 06-xxyyy) or 115°C (all
other TOS converters). When Operating, adequate cooling must be provided to maintain the test point
temperature at or below 125°C (TOS 06-xxyyy) or 115°C (all other TOS converters). Although the
maximum point Temperature of the power modules is 125°C (TOS 06-xxyyy) or 115°C (all other TOS
converters), you can limit this Temperature to a lower value for extremely high reliability.
The unit will shutdown if the thermal reference point exceeds 135°C typ. (TOS 06-xxyyy) or 125°C (all
other TOS converters) but the thermal shutdown is not intended as a guarantee that the unit will survive
temperature beyond its rating. The module will automatically restarts after it cools down.

Short Circuitry Protection
Continuous, hiccup and auto-recovery mode.
During short circuit, converter still shut down. The average current during this condition will be very low
and the device can be safety in this condition.
Output over current protection
To provide protection in an over output current condition, the unit is equipped with internal
current-limiting circuitry and can endure current limiting continuously. When the fault condition occurs,
the unit enters hiccup mode.
Hiccup-mode is a method of operation in a power supply whose purpose is to protect the power supply
from being damaged during an over-current fault condition. It also enables the power supply to restart
when the fault is removed.
The typical average output current during hiccup is 2A (TOS 06), 3A (TOS 10) and 3.5A (TOS 16).
Output Voltage Programming
Output voltage can be adjusted from 0.75Vdc to 3.3Vdc (TOS xx-05yyy) or 0.75Vdc to 5.0Vdc (TOS
xx-12yyy) by connecting an external resistor between Trim and GND pins. Without this external resistor,
the output voltage will be 0.75Vdc. Using the following equation to calculate the value of external
resistor for desired output voltage.

Remote Sense
To minimum the effects of distribution losses by regulating the voltage at the Remote Sense pin. The
voltage between the Sense pin and Vo pin must not exceed 0.5V.
When using Remote Sense, the output voltage of the module can increase, which if the same output
current is maintained, the output power of the module increase, too. Make sure that the output power of
the module at or below the maximum rated power. When the Remote Sense feature is not being used,
leave the Remote Sense pin unconnected.
Remote Sense circuit configuration
Remote ON/OFF Control
Two remote ON/OFF control logic options are available for TOS xx-xxSM and TOS xx-xxSIL.
Positive logic On/Off signal, device code suffix “-P”, turns the module ON during a logic High on the
On/Off pin and turns OFF during a logic Low. Negative logic On/Off signal, no device code suffix, turns
the module OFF during a logic High on the On/Off pin and turns ON during a logic Low.
The On/Off pin is an open collector/drain logic input signal (Von/off) that referenced to GND.

Input Filtering
TOS 06-05SM / TOS 06-05SIL module should be connected to a low impedance DC source. A highly inductive source
can affect the stability of the module. To make sure the module is stable, input capacitor is necessary that minimize
input ripple voltage of the module.
TOS 06-05yyy: To minimize input voltage ripple, 2 × 150µF low-ESR polymer capacitors in parallel with 2 × 47µF
ceramic capacitors are recommended at the input of the module.
TOS 06-12yyy: To minimize input voltage ripple, 2 × 47µF low-ESR tantalum capacitors in parallel with 2 × 22µF
very low-ESR ceramic capacitors are recommended at the input of the module.
TOS 10-05yyy: To minimize input voltage ripple, 3 × 150µF low-ESR polymer capacitors in parallel with 2 × 47µF
ceramic capacitors are recommended at the input of the module.
TOS 10-12yyy: To minimize input voltage ripple, 4 × 47µF low-ESR tantalum capacitors in parallel with 4 × 22µF
very low-ESR ceramic capacitors are recommended at the input of the module.
TOS 16-05yyy: To minimize input voltage ripple, 4 × 150µF low-ESR polymer capacitors in parallel with 4 × 47µF
ceramic capacitors are recommended at the input of the module.
TOS 16-12yyy: To minimize input voltage ripple, 6 × 47µF low-ESR tantalum capacitors in parallel with 6 × 22µF
very low-ESR ceramic capacitors are recommended at the input of the module.
Output Filtering
For low output ripple voltage, output capacitor with 1µF ceramic and 10µF tantalum capacitors are needed to comply
with the published ripple and noise specifications.
To reduce the output ripple and improve the dynamic response to a step load change, additional capacitance at the
output can be used. Low ESR polymer and ceramic capacitors are recommended to improve the dynamic response
of the module. For stable operation of the module, limit the capacitance to less than the maximum output capacitance
as specified in the output specification table.

Safety and Installation Instruction
Fusing Consideration
Caution: This power module 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 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 normal-blow fuse with maximum rating of 6A (TOS 06), 15A (TOS 10) and 20A (TOS 16).
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. Refer to the fuse manufacturer’s data for further information.
