SP6134H
High Voltage, 600kHz Synchronous PWM Step Down
Controller
January 2009
Rev. 2.0.0
GENERAL DESCRIPTION
The SP6134H is a 600kHz constant frequency,
voltage mode, synchronous PWM step down
controller optimized for high efficiency.
The SP6134H 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 SP6134H can accommodate type
II and type III compensation schemes.
Protection features include a programmable
UVLO, thermal shutdown and output short
circuit protection.
The SP6134H 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 SP6134,
SP6132, SP6132H, SP6137 and SP6139 for
complete details.
The SP6134H is available in lead free, RoHS
compliant,
space
saving
10-pin
MSOP
