YEV09T03 3A DC-DC POL Converter

where:
VOUT = Desired (trimmed) value of output voltage V
RTRIM = Required value of the trim resistor in k
If the RTRIM is not used, the output voltage of the POL
converter will be 0.591V.
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 1)
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 (0.4V max) or
connected to GND.
The ON/OFF pin should be controlled with an open
collector transistor as shown in Figure 13.

Protections
6.4.1
Input Undervoltage Lockout
The POL converter will shut down when the input
voltage drops below a predetermined voltage. It will
start automatically when the input voltage exceeds
the specified threshold.
6.4.2
Output Overcurrent Protection
The POL converter is protected against overcurrent
and short circuit conditions.
Upon sensing an
overcurrent condition, the POL converter will enter
hiccup mode of operation. Once the overload or
short circuit condition is removed, the POL converter
will automatically restart and Vout will return to its
nominal value.

Characterization

Ripple and Noise
The output voltage ripple and input reflected ripple
current waveforms are measured using the test
setup shown in Figure 14.

Safety
The YEV09T03 POL converters do not provide
isolation from input to output. The input devices
powering YEV09T03 must provide relevant isolation
requirements according to all IEC60950 based
standards. Nevertheless, if the system using the
converter needs to receive safety agency approval,
certain rules must be followed in the design of the
system.
In particular, all of the creepage and
clearance requirements of the end-use safety
requirements
must
be
observed.
These
requirements are included in UL60950 - CSA60950-
00 and EN60950, although specific applications may
have other or additional requirements.
The YEV09T03 POL converters have no internal
fuse.
If required, the external fuse needs to be
