advertisement Dual Output Monolithic Synchronous Buck Regulator Operates
from 3.6V to 15V Inputs and Delivers 3A Per Channel вЂ“ Design Note 1020
Tom Gross
Introduction
The LTC3633 is a high efficiency, dual output monolithic
synchronous step-down switching regulator, capable of
delivering 3A of output current per channel from input
voltages between 3.6V and 15V. Its compact 4mm Г— 5mm
QFN package has very low thermal impedance eliminating
the need for an external heat sink. Its high input voltage
capability makes the LTC3633 ideal for 12V distributed
power systems.
1.8V and 3.3V 2MHz Buck Regulator
Figure 1 shows a LTC3633 12VIN to 1.8VOUT and 3.3VOUT,
3A, buck regulator. With the frequency setting pin, RT,
connected to the internal 3.3V regulator rail (INTVCC), this
circuit runs at 2MHz вЂ”the LTC3633 switching frequency
is programmable from 500kHz to as high as 4MHz, and
can also be synchronized to an external clockвЂ”reducing
the value and size of the output capacitors and inductor.
Even with this high switching frequency, the efficiency of
this circuit is good: 87% at full load for the 3.3V regulator and 82% at full load for the 1.8V regulator, at 12VIN
(see Figure 2). …
