HTD1R5N Series DC-DC Converter
1.0 DESCRIPTION
1.1 FEATURES
The HTD Series of high temperature DC-DC converters is
specifically designed for extreme temperature environments.
• Non-Isolated
• 1.5 W rated output power
• Wide input voltage range
• Low noise
Hybrid microcircuit technology provides superior reliability in high
temperature applications. Bare semiconductor die are integrated
with passive components using thick film conductors on a
ceramic substrate. A hermetic metal package protects internal
components for long term reliability.
• Undervoltage lockout
• Short circuit protection
• Soft start
1.2 HIGH TEMPERATURE CHARACTERIZATION
The HTD1R5N Series utilizes a boundary mode, peak current
controlled flyback topology. The flyback topology achieves high
efficiency at low power levels, over a wide input voltage range.
The main output is tightly regulated with a wide bandwidth,
precision voltage control loop.
• Guaranteed performance to 185 °C operating
1.3 MANUFACTURING AND COMPLIANCE
• Manufactured in a MIL-PRF-38534 Class H and Class K facility
• MIL-STD-883
• ISO-9001
High temperature performance is guaranteed through screening,
product qualification, component lot testing and analysis. The
HTD Series has been characterized over the full operating
temperature range from -55 °C to +185 °C, including electrical
performance, operating life, temperature cycling, mechanical
shock and vibration.
1.4 PACKAGING
• Low-profile: 0.975” x 0.800” x 0.270”
• Max weight: 11 g
• Industry standard pinout
• Precision projection-welded hermetic metal case
The HTD Series is intended for harsh environments including
down-hole oil and gas, MWD/LWD and wireline logging tools,
aircraft engine electronics, and other industrial applications.
