SP6134 - 600kHz Synchronous PWM Step Down Controller

Description

The SP6134 is a 600kHz constant frequency, voltage mode, synchronous PWM step down controller optimized for high efficiency.

The SP6134 is adequately suited for split plane applications utilizing a low power 5V rail to power the controller circuitry, minimizing power dissipation.

Features

  • include a programmable UVLO, thermal shutdown and output short circuit protection. The SP6134 is part of a larger family of step down controllers operating at various switching frequencies up to 1300kHz and input voltages up to 28V. Refer to Exar’s SP6134H, SP6132, SP6132H, SP6137 and SP6139 for complete detail.

January 2009 SP6134 600kHz Synchronous PWM Step Down Controller Rev. 2.0.0 GENERAL DESCRIPTION The SP6134 is a 600kHz constant frequency, voltage mode, synchronous PWM step down controller optimized for high efficiency. The SP6134 is adequately suited for split plane applications utilizing a low power 5V rail to power the controller circuitry, minimizing power dissipation. Its wide input voltage range of 3V to 15V allows for conversions from the standard 3.3V, 5V, 9.6V and 12V power rails to an output voltage adjustable down to 0.8V. Developed around a wide bandwidth internal amplifier, the SP6134 can accommodate type II and type III compensation schemes. Protection features include a programmable UVLO, thermal shutdown and output short circuit protection.
