PT6100 Series

1 Amp Adjustable Positive Step-down

Integrated Switching Regulator

SLTS029A

(Revised 6/30/2000)

The PT6100 Series is a line of High-Perfor-

mance 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.

• 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

* 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.
