LSP5504
PWM Control 2A Step-Down Converter
1/10
Ver.1.1
Typical Application Circuit
LSP5504
Vout=5V/2A
Applications
Cellular Phones
PC Motherboard
LCD Monitor
Graphic Card
DVD-Video Player
Telecom Equipment
ADSL Modem
Networking power supply
Microprocessor core supply
Printer and other Peripheral Equipment
General Description
The LSP5504 is high efficiency, simple to use, 2A
step-down
regulator
flexible
enough
to
be
optimized for a variety of applications.
LSP5504
provides
low-ripple
power,
high
efficiency, and excellent transient characteristics.
The PWM control circuit is able to vary the duty
ratio linearly from 0 up to 100%. This converter
also contains an error amplifier circuit as well as a
soft-start circuit that prevents overshoot at startup.
An
enable function, an
over current
protect
function and a short circuit protect function are
built inside, and when OCP or SCP happens, the
operation frequency will be reduced from 300KHz
to 50KHz. Also, an internal compensation block is
built in to minimum external component count.
With the addition of an internal buffer driver, a coil,
capacitors, and resistors connected externally,
these ICs can function as step-down switching
regulators. They serve as ideal power supply units
for portable devices when coupled with the SOP-8L
mini-package, providing such outstanding features
as low current consumption. Since this converter
can accommodate an input voltage up to 18V, it is
also suitable for the operation via an AC adapter.
Features
Input voltage: 3.6V to 18V.
Output voltage: 0.8V to VCC.
Duty ratio: 0% to 100% PWM control
Oscillation frequency: 300KHz typ.
Soft-start, Current limit, Enable function
Thermal Shutdown function
SOP-8L Package.
