PART NUMBER: VPOL15A-5-SIP
5.7 UVLO (Under-Voltage Lockout)
The voltage on the Vcc pin determines the start of the operation of the
Converter. When the input Vcc rises and exceeds about 2.8V the
converter initiates a soft start. The UVLO function in the converter has a
hysteresis (about 100mV) built in to provide noise immunity at start-up.
6. Safety
6.1 Input Fusing and Safety Considerations.
Agency Approvals: The power supply shall be submitted to and receive
formal approval from the following test agencies.
1.The power supply shall be approved by a nationally recognized testing
laboratory to UL/CSA 60950 3
(International)
2. CB Certificate from an internationally recognized test house in
accordance with EN 60950.
The VPOL15A-5-SIP series converters do not have an internal fuse.
However, to achieve maximum safety and system protection, always
use an input line fuse. The safety agencies require a time-delay fuse
with a maximum rating of 20A.

7. Applications
7.1 Layout Design Challenges.
In optimizing thermal design the PCB is utilized as a heat sink. Also
some heat is transferred from the VPOL15A-5-SIP module to the main
board through connecting pins. The system designer or the end user
must ensure that other components and metal in the vicinity of the
VPOL15A-5-SIP series meet the spacing requirements to which the
system is approved.
Low resistance and low inductance PCB layout traces are the norm and
should be used where possible. Due consideration must also be given to
proper low impedance tracks between power module, input and output
grounds. The recommended VPOL15A-5-SIP footprint is shown as figure
