HIP6012CBS2462

Special Purpose Regulators Overview

The HIP6012CBS2462 is a switching controller designed for synchronous rectifier buck converters in microprocessor applications. It operates from +5V or +12V inputs and utilizes voltage-mode pulse width modulation (PWM) control. The device features a free-running triangular wave oscillator with a maximum switching frequency of 1000kHz, adjustable from below 50kHz to over 1MHz. It includes an error amplifier with high gain bandwidth for fast transient response and monitors current by sensing the upper MOSFET's on-resistance. The package is a 14-pin Plastic Dual Small Outline (PDSO14/SOIC-14).
