3 Amp Adjustable Positive Step-down
Integrated Switching 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 100A.
Standard Application
C1 = Optional 1F ceramic
C2 = Required 100F electrolytic (1)
Q1 = NFET

Notes:
(1) The PT6300 Series requires a 100F 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.
