advertisement Monolithic Synchronous Step-Down Regulator Delivers up to 12A
from a Wide Input Voltage Range вЂ“ Design Note 457
Charlie Zhao and Henry Zhang
Typical Application Example
Figure 1 shows a typical application schematic of the
LTC3608. This 7mm Г— 8mm regulator supplies 2.5V at 8A
maximum load current from a 4.5V to 20V input source.
This application switches at a nominal 650kHz, which
allows the use of low proп¬Ѓle inductor and capacitors while
maintaining high efп¬Ѓciency. The switching frequency can
be easily adjusted by a resistor (RON in Figure 1, connected
to the ION pin). Figure 2 shows the operating efп¬Ѓciency. Introduction
The LTC В®3610 is a high power monolithic synchronous step-down DC/DC regulator that can deliver up
to 12A of continuous output current from a 4V to 24V
(28V maximum) input supply. It is a member of a high
current monolithic regulator family (see Table 1) that
features integrated low RDS(ON) N-channel top and bottom MOSFETs. This results in a high efп¬Ѓciency and high
power density solution with few external components.
This regulator family uses a constant on-time valley
current mode architecture that is capable of operating
at very low duty cycles at high frequency and with very
fast transient response. All are available in low proп¬Ѓle
(0.9mm max) QFN packages. The FCB pin is connected to ground to force continuous …

LвЂ‰DESIGN IDEAS 32VIN Synchronous Buck Regulators
with Integrated FETs Deliver up to 12A
from Sub-1mm Height Packages
by Stephanie Dai and Theo Phillips
Introduction
Monolithic buck regulators are easy
to hook up and they make it possible
to squeeze an entire DC/DC converter
into very tight spaces. Although monolithics are an easy fit, they arenвЂ™t the
perfect fit for every application. For
instance, they typically lack the capability to efficiently convert high input
voltages (>12V) to low voltages at high
output currents (>4A), thus leaving the
job to a traditional controller IC and
external MOSFETs.
A new family of devices, though,
offers the advantages of monolithics
with the low duty cycle and high efficiency of discrete components. The
LTC3608, LTC3609, LTC3610 and
LTC3611 are synchronous buck converters that bring high power density
and simplified design to point-of-load
applications. With a maximum input of A new family of devices
offers the advantages of …
