Description
The SKY81290 is a high efficiency, 1.2 A high current boost converter with a programmable constant current sink. It is an ideal power solution for LED photo flash applications in all single cell, Li-ion powered products. The SKY81290 maintains output current regulation by switching the internal high-side and low-side switch transistors. The transistor switches are pulse-width modulated at a fixed frequency of 2.0 MHz. The high switching frequency allows the use of a small...
