General Description
The LP3204 is a constant frequency, current mode,
PWM step-down converter. The device integrates a
main switch and a synchronous rectifier for high
efficiency. The 2.5V to 5.5V input voltage range
makes the LP3204 is ideally suited for portable
electronic devices that are powered from 1-cell
Li-ion battery or from other power sources within
the range such as cellular phones, PDAs and
handy-terminals.
Internal synchronous rectifier with low RDS(ON)
dramatically reduces conduction loss at PWM mode.
The
efficiency while eliminate the need for an external
Schottky diode.The switching ripple is easily
smoothed-out by small package filtering elements
due to a fixed operation frequency of 1.5MHz. This
along with small SOT-23-5 package provide small
PCB area application. Other features include soft
start, lower internal reference voltage with 2%
accuracy, over temperature protection, and over
current protection.
