DESCRIPTION
5V Step-Down
Switching Regulator
The LT1076-5 is a 2A xed 5V output monolithic bipolar
switching regulator which requires only a few external parts
for normal operation. The power switch, all oscillator and
control circuitry, all current limit components, and an output
monitor are included on the chip. The topology is a classic
positive “buck” conguration but several design innova-
tions allow this device to be used as a positive-to-negative
converter, a negative boost converter, and as a yback con-
verter. The switch output is specied to swing 40V below
ground, allowing the LT1076-5 to drive a tapped inductor
in the buck mode with output currents up to 4A.
The LT1076-5 uses a true analog multiplier in the feedback
loop. This makes the device respond nearly instantaneously
to input voltage uctuations and makes loop gain indepen-
dent of input voltage. As a result, dynamic behavior of the
regulator is signicantly improved over previous designs.
On-chip pulse by pulse current limiting makes the LT1076-
5 nearly bust-proof for output overloads or shorts. The
input voltage range as a buck converter is 8V to 60V, but
a self-boot feature allows input voltages as low as 5V in
the inverting and boost congurations.
The LT1076-5 is available in a low cost 5- and 7-lead TO-
220 packages with frequency pre-set at 100kHz and current
limit at 2.6A. See Application Note 44 for design details.
