3 Amp Adjustable Positive Step-down

Integrated Sw itching Regulators

PT6300 Series

• 90% Efficiency

• Adjustable Output Voltage

• 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

(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 effi-

ciency with open-collector on/off

control and adjustable output voltage.

Quiescent current in the shutdown

mode is typically less than 100µA.

Standard Application

C1 = Optional 1µF ceramic

C2 = Required 100µF electrolytic (1)

Q1 = NFET

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.
