ME2182
2A, 1.2MHz Synchronous Step-Up DC/DC Controller
Description
The ME2182 is synchronous, 2A,1.2MHZ step-up DC-DC controller , which mainly consists of a reference
voltage source, an oscillation circuit, an error amplifier, a phase compensation circuit, a PWM / PFM switching control circuit and an adjustable output current limit circuit. With an external low-on-resistance Nch Power MOS and Pch Power MOS. This product is ideal for applications requiring high efficiency and a high output current.
