LM27222 Texas Instruments TI pdf datasheet download
LM27222
High-Speed 4.5A Synchronous MOSFET Driver
General Description
The LM27222 is a dual N-channel MOSFET driver designed
to drive MOSFETs in push-pull configurations as typically
used in synchronous buck regulators. The LM27222 takes
the PWM output from a controller and provides the proper
timing and drive levels to the power stage MOSFETs. Adaptive
shoot-through protection prevents damaging and efficiency
reducing shoot-through currents, thus ensuring a robust
design capable of being used with nearly any MOSFET.
The adaptive shoot-through protection circuitry also reduces
the dead time down to as low as 10ns, ensuring the highest
operating efficiency. The peak sourcing and sinking current
for each driver of the LM27222 is about 3A and 4.5Amps
respectively with a Vgs of 5V. System performance is also
enhanced by keeping propagation delays down to 8ns. Efficiency
is once again improved at all load currents by supporting
synchronous, non-synchronous, and diode emulation
modes through the LEN pin. The minimum output pulse
width realized at the output of the MOSFETs is as low as
30ns. This enables high operating frequencies at very high
conversion ratios in buck regulator designs. To support low
power states in notebook systems, the LM27222 draws only
5μA from the 5V rail when the IN and LEN inputs are low or
floating.
Features
n Adaptive shoot-through protection
n 10ns dead time
n 8ns propagation delay
n 30ns minimum on-time
n 0.4Ω pull-down and 0.9Ω pull-up drivers
n 4.5A peak driving current
n MOSFET tolerant design
n 5μA quiescent current
n 30V maximum input voltage in buck configuration
n 4V to 6.85V operating voltage
n SO-8 and LLP packages
Applications
n High Current Buck And Boost Voltage Converters
n Fast Transient DC/DC Power Supplies
n Single Ended Forward Output Rectification
n CPU And GPU Core Voltage Regulators

LM4860 Series 1W Audio Power Amplifier with Shutdown Mode
General Description
The LM4860 is a bridge-connected audio power amplifier
capable of delivering 1W of continuous average power to an
8Ω load with less than 1% THD+N over the audio spectrum
from a 5V power supply.
Boomer audio power amplifiers were designed specifically to
provide high quality output power with a minimal amount of
external components using surface mount packaging. Since
the LM4860 does not require output coupling capacitors,
bootstrap capacitors or snubber networks, it is optimally
suited for low-power portable systems.
The LM4860 features an externally controlled, low-power
consumption shutdown mode, as well as an internal thermal
shutdown protection mechanism. It also includes two headphone
control inputs and a headphone sense output for
external monitoring.
The unity-gain stable LM4860 can be configured by external
gain setting resistors for differential gains of up to 10 without
the use of external compensation components. Higher gains
may be achieved with suitable compensation.
Key Specifications
n THD+N at 1W continuous average
output power into 8Ω: 1% (max)
n Instantaneous peak output power: >2W
n Shutdown current: 0.6μA (typ)
Features
n No output coupling capacitors, bootstrap capacitors, or
snubber circuits are necessary
n Small Outline (SO) packaging
n Compatible with PC power supplies
n Thermal shutdown protection circuitry
n Unity-gain stable
n External gain configuration capability
n Two headphone control inputs and headphone sensing
output
Applications
n Personal computers
n Portable consumer products
n Cellular phones
n Self-powered speakers
n Toys and games

LM2596
LM2596 SIMPLE SWITCHER Power Converter 150 kHz3A Step-Down Voltage
Regulator
General Description
The LM2596 series of regulators are monolithic integrated
circuits that provide all the active functions for a step-down
(buck) switching regulator, capable of driving a 3A load with
excellent line and load regulation. These devices are available
in fixed output voltages of 3.3V, 5V, 12V, and an adjustable
output version.
Requiring a minimum number of external components, these
regulators are simple to use and include internal frequency
compensation†, and a fixed-frequency oscillator.
The LM2596 series operates at a switching frequency of
150 kHz thus allowing smaller sized filter components than
what would be needed with lower frequency switching regulators.
Available in a standard 5-lead TO-220 package with
several different lead bend options, and a 5-lead TO-263
surface mount package.
A standard series of inductors are available from several
different manufacturers optimized for use with the LM2596
series. This feature greatly simplifies the design of
switch-mode power supplies.
Other features include a guaranteed ±4% tolerance on output
voltage under specified input voltage and output load
conditions, and ±15% on the oscillator frequency. External
shutdown is included, featuring typically 80 μA standby current.
Self protection features include a two stage frequency
reducing current limit for the output switch and an over
temperature shutdown for complete protection under fault
conditions.
Features
n 3.3V, 5V, 12V, and adjustable output versions
n Adjustable version output voltage range, 1.2V to 37V
±4% max over line and load conditions
