LSI Controls Inc. AcuWatt Switching Regulator LS78ST1xx - Drop-in replacement for PT78ST1xx

Description
LSI Controls, Inc., introduces its small footprint, high efficiency, Integrated Switching Regulators. With a 33% greater current rating (2A continuous / 3A peak), the LS78ST1xx regulators are higher power pin compatible drop-in replacements for the now obsolete TI/Power Trends PT78ST1xx. The LS78ST1xx follows the same pinout and footprint as the PT78ST1xx. The installed surface mount height of the LSI equivalent is only 0.17" taller to deliver additional current capacity. It can be configured as a thru Hole (Horizontal or Vertical) or Surface mount device. The regulator module boasts a high-output-current PWM converter that integrates a low resistance, high side N-Channel MOSFET and offers a wide input voltage range of +5.5 to 36VDC. The LS78ST1xx regulators run cool with conversion efficiencies up to 95%, and provides built-in current limiting, over voltage protection, and thermal shutdown safety features. Operating range is -40⁰C to 80⁰C with storage from -40⁰C to 125⁰C. The device also features a high performance voltage amplifier that provides tight voltage regulation accuracy under transient conditions, as well as an under voltage lockout feature that prevents startup until the input voltage reaches the minimum supply level. It also incorporates a slow-start circuit to limit inrush currents and a voltage feed forward circuit to improve transient response.
