2 AMP ADJUSTABLE POSITIVE STEP-DOWN

INTEGRATED SWITCHING REGULATOR

• 87% Efficiency

Switching Regulator (ISR) designed to

• Adjustable Output Voltage

• Internal Short Circuit Protection

• Over-Temperature Protection

• On/Off Control (Ground Off)

• Small SIP Footprint

meet the on-board power conversion

needs of battery powered or other equip-

ment requiring high efficiency and

small size. This high performance ISR

offers a unique combination of features

combining 87% typical efficiency with

open-collector on/off control and ad-

justable output voltage.

• Wide Input Range

The PT6310 series is a High-

Performance 2 Amp, 12-Pin SIP

(Single In-line Package) Integrated

Quiescent current in the shutdown

mode is typically less than 100µA.

ISR will operate to no load with reduced specifications.

** Input voltage cannot exceed 30V when the inhibit function is used.

Note: The PT6310 requires a 100µF electrolytic or tantalum output capacitor for proper operation in all applications.
