Wide Input, 900kHz Synchronous PWM Step Down Controller
Rev. 2.0.0
GENERAL DESCRIPTION
The SP6137 is a 900kHz constant frequency, voltage mode, synchronous PWM step down controller optimized for high efficiency.
The SP6137 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 SP6137 can acmodate type II and type III pensation schemes.
