REV. MAY 07, 2004
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 uses 100% surface-
mount construction for maximum reliability and features 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.
