LM2611 - 1.4MHz Cuk Converter

Download the LM2611 datasheet PDF. This datasheet also covers the LM2 variant, as both devices belong to the same 1.4mhz cuk converter family and are provided as variant models within a single manufacturer datasheet.

General Description

The LM2611 is a current mode, PWM inverting switching regulator.

(36-VIN(MAX)).

Key Features

  • a shutdown pin, which can be activated when the part is not needed to lower the Iq and save battery life. A negative feedback (NFB) pin provides a simple method of setting the output voltage, using just two resistors. Cycle-by-cycle current limiting and internal compensation further simplify the use of the LM2611. The LM2611 is available is a small SOT23-5 package. It comes in two grades: Grade A Current Limit RDS(ON) 1.2A 0.5Ω Grade B 0.9A 0.7Ω Features n n n n n n n n n 1.4MHz switching frequ.

LM2611 1.4MHz Cuk Converter January 2002 LM2611 1.4MHz Cuk Converter General Description The LM2611 is a current mode, PWM inverting switching regulator. Operating from a 2.7 - 14V supply, it is capable of producing a regulated negative output voltage of up to −(36-VIN(MAX)). The LM2611 utilizes an input and output inductor, which enables low voltage ripple and RMS current on both the input and the output. With a switching frequency of 1.4MHz, the inductors and output capacitor can be physically small and low cost. High efficiency is achieved through the use of a low RDS(ON) FET. The LM2611 features a shutdown pin, which can be activated when the part is not needed to lower the Iq and save battery life.
