TPS61120

illustrate

The TPS6112x device provides a complete power solution for products powered by a single cell of lithium-ion or lithium-polymer or two to four alkaline batteries, nickel-cadmium or nickel-metal hydride batteries. These devices can produce two stable outputs that are either externally adjusted by a resistor divider or a voltage fixed inside the chip. It also provides a maximum output of at least 200 mA for power generation from the supply voltage down to the current 3.3 to 1.8 five, and the fifth section of the Section 1 lithium-ion or lithium-polymer battery comes out of a simple solution to implement a boost converter is a fixed frequency-based, pulse-width modulation (PWM) controller using a synchronous rectifier for maximum benefit. The boost switch for the maximum peak current is limited to a value of 1600 mA.

Device application

• All single lithium or dual batteries or products powered by MP-3 players, handheld computers USB, and other portable devices
