* ISR will operate to no load with reduced specifications.
** Input voltage cannot exceed 30V when the inhibit function is used. *** See Thermal Derating chart.
Note:
The PT6320 Series requires a 100μF electrolytic or tantalum output capacitor for proper operation in all applications.

Low Voltage Input (7V)
90% Efficiency
Adjustable Output Voltage
Internal Short Circuit Protection
Over-Temperature Protection
On/Off Control (Ground Off)
The PT6320 series is a low volt-
age input (typically 7V) version of
Power Trends’ high-performance
3A, 12 pin SIP Integrated Switching
Regulators (ISRs). These ISRs are de-
signed with premium low threshold FETs
for those applications requiring very low
input/output voltage differentials such as
battery powered equipment. 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.
