The TS2122 is a dual high-efficiency PWM step-
down DC-DC converter. It is capable of delivering
700mA output each channel over a wide input
voltage from 2.5V to 5.5V, the TS2122 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 other handheld devices. 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 WDFN-12L 3X3 package provides small PCB
area application. Other features include soft
start, lower internal reference voltage with 2%
accuracy, over temperature protection, and over
current protection.
