SIP/SIE 500
NON-ISOLATED SERIES
DESCRIPTION
SIP/SIE non-isolated step-down DC/DC converters
deliver high efficiency and excellent transient response in
an industry standard SIP package. The SIP/SIE series
has output voltages ranging from 1.2 to 3.3V and up to 6
amps of output current. The SIE model has power OK
and remote sense pins for added flexibility and improved
point of load regulation. The SIP/SIE series is available
for vertical or horizontal mounting. The SIP/SIE series
use 100% surface-mount construction for maximum
reliability and feature over seven million hours MTBF.

Notes
† MTBF predictions may vary slightly from model to model.
Specifications typically at 25°C, normal line, and full load, unless
otherwise stated.
Soldering Conditions: I/O pins, 260°C, ten seconds; fully
compatible with commercial wave-soldering equipment.
Safety: Agency approvals may vary from model to model. Please
consult factory for specific model information.
Units are water-washable and fully compatible with commercial
spray or immersion post wave-solder washing equipment.
