Introduction

AI Translation

CJ9112T6 is a compact, high-efficiency, fixed frequency, synchronous step-up DCDC converter. This device provides an easy-to-use power supply solution for applications powered by either one-cell, two-cell or three-cell alkaline, NiCd, NiMH, one-cell LiIon or Li-Polymer batteries. A low-voltage technology allows the regulator to start up without high inrush current or output voltage overshoot from a low voltage input. High efficiency is accomplished by integrating the low-resistance N-Channel boost switch and synchronous P-Channel switch. All compensation and protection circuitry are integrated to minimize external components. The devices provide a true disconnect from input to output (CJ9112T6A) or an input-to-output bypass (CJ9112T6B), while in shutdown state. Output voltage is set by a small external resistor divider.
