YNM05S05 DC-DC Converter Data Sheet
3.0-5.5 VDC Input; 0.7525-3.63 VDC Programmable @ 5 A
Output Voltage Programming (Pin 3)
The output voltage can be programmed from
0.7525 V to 3.63 V by connecting an external resistor
between TRIM pin (Pin 3) and GND pin (Pin 4); see
Fig. D. Note that when a trim resistor is not
connected, the output voltage of the converter is
The output voltage can also be programmed by an
external voltage source. To make trimming less
sensitive, a series external resistor Rext is
recommended between the TRIM pin and the
programming voltage source. Control Voltage can be
calculated by the formula:
0.7525 V.

A trim resistor, R TRIM , for a desired output voltage
can be calculated using the following equation:

Note that the tolerance of a trim resistor directly
affects the output voltage tolerance. It is

Ground pin of the trim resistor should be connected
directly to the converter GND pin with no voltage
drop in between. Table 1 provides the trim resistor
values for popular output voltages.

Protection Features
Input Undervoltage Lockout
Input undervoltage lockout is standard with this
converter. The converter will shut down when the
input voltage drops below a pre-determined voltage;
it will start automatically when Vin returns to a
specified range.
The input voltage must be typically 2.3 V for the
converter to turn on. Once the converter has been
turned on, it will shut off when the input voltage
drops below typically 2.2 V.
Output Overcurrent Protection (OCP)
The converter is protected against overcurrent and
short circuit conditions. Upon sensing an overcurrent
condition, the converter will enter hiccup mode. Once
over-load or short circuit condition is removed, Vout
will return to nominal value.
