Pin-Out Information
PT6100 Series
• 90% Efficiency
• Adjustable Output Voltage
• Internal Short Circuit Protection
• Over-Temperature Protection
• On/Off Control (Ground Off)
• Small SIP Footprint
• Meets Requirements for FCC
Part 15; Class B limits for Radiated
Emissions
• Wide Input Range
The PT6100 Series is a line of HighPerformance 1 Amp, 12-Pin SIP (Single In-line
Package) Integrated Switching Regulators (ISRs)
designed to meet the on-board power conversion
needs of battery powered or other equipment
requiring high efficiency and small size. This high
performance ISR family offers a unique
combination of features combining 90% typical
efficiency with open-collector on/off control and
adjustable output voltage. Quiescent current in
the shutdown mode is less than 100µA.

* ISR will operate down to no load with reduced specifications.
** Input voltage cannot exceed 30V when the inhibit function is used. ***See Thermal Derating chart.
Note:
The PT6100 Series requires a 100µF electrolytic or tantalum output capacitor for proper operation in all applications.
