SLTS230C–NOVEMBER 2004–REVISED SEPTEMBER 2008 1.5-A, WIDE-INPUT ADJUSTABLE SWITCHING REGULATOR 1 FEATURES DESCRIPTION • 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 • On/Off Inhibit smaller and lighter than its predecessors, and has • Undervoltage Lockout either similar or improved electrical performance • Output Current Limit characteristics. The case-less, double-sided package, also exhibits improved thermal characteristics, and is • Overtemperature Shutdown compatible with TI's roadmap for RoHS and lead-free • Operating Temperature: –40°C to 85°C compliance. • Surface Mount Package Available Operating from a wide-input voltage range, the PTN78000 provides high-efficiency, step-down APPLICATIONS 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 STANDARD APPLICATION 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 V 1 5 O operation down to 15 V, with an output voltage of 1 12 V. V PTN78000 I 2 The PTN78000 has undervoltage lockout and an (Top View) + integral on/off inhibit. The modules are suited to a Inhibit 3 4 wide variety of general-purpose applications that (A) C O operate off 12-V, 24-V, or 28-V power.
