PT6300 Series

3 Amp Adjustable Positive Step-down

Integrated Sw itching Regulators

SLTS031B

(Revised 9/30/2000)

•

90% Efficiency

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 effi-

ciency with open-collector on/off

control and adjustable output voltage.

Quiescent current in the shutdown

mode is typically less than 100µA.

Internal Short Circuit Protection

Over-Temperature Protection

On/Off Control (Ground Off)

Small SIP Footprint

Wide Input Range

The PT6300 Series is a line of

High-Performance 3 Amp, 12-Pin SIP

Notes: (1) The PT6300 Series requires a 100µF electrolytic or tantalum output capacitor for proper operation in all applications.

(2) The ISR will operate to no load with reduced specifications.

(3) Input voltage cannot exceed 30V when the inhibit function is used.

(4) See Thermal Derating charts.

(5) Consult the related application note for guidance on adjusting the output voltage.
