LM3152 - (LM3151 - LM3153) SIMPLE SWITCHER CONTROLLER

Download the LM3152 datasheet PDF. This datasheet also covers the LM3151 variant, as both devices belong to the same (lm3151 - lm3153) simple switcher controller family and are provided as variant models within a single manufacturer datasheet.

General Description

The LM3151/2/3 SIMPLE Controller is an easy to use and simplified step down power controller capable of providing up to 12A of output current in a typical application.

Key Features

  • a fixed output voltage of 3.3V, and features switching frequencies of 250 kHz, 500 kHz, and 750 kHz. The synchronous architecture provides for highly efficient designs. The LM3151/2/3 controller employs a Constant On-Time (COT) architecture with a proprietary Emulated Ripple Mode (ERM) control that allows for the use of low ESR output capacitors, which reduces overall solution size and output voltage ripple. The Constant On-Time (COT) regulation architecture allows for fast transient response an.
