The TD1583 is a 380 KHz fixed frequency monolithic
step down switch mode regulator with a built in internal
Power MOSFET. It achieves 3A continuous output
current over a wide input supply range with excellent
load and line regulation.
The device includes a voltage reference, oscillation
circuit, error amplifier, internal PMOS and etc.
The PWM control circuit is able to adjust the duty ratio
linearly from 0 to 100%. An enable function, an over
current protection function and a short circuit protection
function are built inside. An internal compensation block
is built in to minimize external component count.
The TD1583 serves as ideal power supply units for
Applications
Portable DVD
LCD Monitor / TV
Battery Charger
ADSL Modem
Telecom / Networking Equipment
