Data Sheet
where:
RTRIM = Required value of trim resistor in k
VOUT = Desired (trimmed) value of output voltage V
If the RTRIM is not used and the Sense+ and Sense-
pins are shorted to VOUT and GND respectively, the
output voltage of the POL converter will be 0.6V. No
capacitor is allowed between Trim+ and Trim- pins.
Note that the trim resistor tolerance directly affects
the output voltage accuracy. It is recommended to
use ±0.1% trim resistors to meet the output voltage
setpoint accuracy specified in p. 4.2.

ON/OFF (Pin 6)
The ON/OFF pin is used to turn the POL converter
ON or OFF remotely by a signal from a system
controller. For positive logic, the POL converter is
ON when the ON/OFF pin is at a logic high (2.4V
min) or left open. The POL converter is OFF when
the ON/OFF pin is at a logic low (1.2V max) or
connected to GND.
The typical connections are shown in Figure 17.

converter and the load. The Sense- (Pin 10) and
Sense+ (Pin 11) pins should be connected at the

If remote sensing is not required, the Sense pins
must be connected
directly at the output of the POL converter.

The voltage sense traces should be located close to
a ground plane to minimize system noise.
When using remote sense, the output voltage at the
converter can be increased by up to 0.5V

the maximum output voltage measured directly
between the VOUT and GND pins shall not exceed
3.63V. In addition it is the user’s responsibility to
ensure the POL converter’s actual output power
always remains at or below the maximum allowable
output power obtained from the derating curves.
