1.5-A, WIDE-INPUT ADJUSTABLE SWITCHING REGULATOR
1.5-A Output Current
Wide-Input Voltage
The
PTN78000
is
a
series
of
high-efficiency,
step-down Integrated Switching Regulators (ISR),
(7 V to 36 V) / (15 V to 36 V)
that represent the third generation in the evolution of
Wide-Output Voltage Adjust
the popular 78ST100 series of products. In new
(2.5 V to 12.6 V) / (11.85 V to 22 V)
designs it should be considered in place of the
High Efficiency (Up to 95%)
78ST100, PT78ST100, PT5100, and PT6100 series
of single in-line pin (SIP) products. The PTN78000 is

characteristics. The case-less, double-sided package,
also exhibits improved thermal characteristics, and is

compliance.
Surface Mount Package Available
Operating from a wide-input voltage range, the
PTN78000
provides
high-efficiency,
step-down
voltage conversion for loads of up to 1.5 A. The
General-Purpose, Industrial Controls,
output voltage is set using a single external resistor.
HVAC Systems, Test and Measurement,
The PTN78000W may be set to any value within the
Medical Instrumentation, AC/DC Adaptors,
range, 2.5 V to 12.6 V, and the PTN78000H from
Vehicles, Marine, and Avionics
11.85 V to 22 V. The output voltage of the
PTN78000W can be as little as 2 V lower than the
input, allowing operation down to 7 V, with an output
voltage of 5 V. The output voltage of the PTN78000H
can be as little as 3 V lower than the input, alowing
operation down to 15 V, with an output voltage of
12 V.
The PTN78000 has undervoltage lockout and an
integral on/off inhibit. The modules are suited to a
wide variety of general-purpose applications that
operate off 12-V, 24-V, or 28-VDC power.
(A) See the Application Information section for
capacitor
recommendations.
The
minimum
input
capacitance is 2.2
F for PTN78000W, and 9.4 F (2
x 4.7
F) for PTN78000H.
(B) RSET is required to adjust the output voltage
higher than 2.5 V for PTN78000W, and high than
11.824 V for PTN78000H. See the Application
Information section for specific values.
