Overview

The LMR61428 is a step-up DC-DC switching regulator for battery-powered and low input voltage systems that can achieve efficiencies up to 90%. It has a wide input voltage range from 1.2V to 14V and a possible regulated output voltage range of 1.24V to 14V. It has an internal 0.17Ω N-Channel MOSFET power switch. The high switching frequency of up to 2MHz of the LMR61428 allows for tiny surface mount inductors and capacitors. Because of the unique constant-dutycycle gated oscillator topology very high efficiencies are realized over a wide load range. The supply current is reduced to 80μA because of the BiCMOS process technology. In the shutdown mode, the supply current is less than 2.5μA. The LMR61428 is available in a VSSOP-8 package. The LMR61428 is designed to provide step-up DC-DC voltage regulation in battery-powered and low-input voltage systems. It combines a step-up switching regulator, N-channel power MOSFET, built-in current limit, thermal limit, and voltage reference in a single 8-pin VSSOP package. The switching DC-DC regulator boosts an input voltage between 1.2V and 14V to a regulated output voltage between 1.24V and 14V that is limited by a fixed maximum duty cylcle of 70%. The LMR61428 starts from a low 1.1V input and remains operational down to 0.65V. This device is optimized for use in cellular phones and other applications requiring a small size, low profile, as well as low quiescent current for maximum battery life during stand-by and shutdown. A high-efficiency gatedoscillator topology offers an output of up to 1A. Additional features include a built-in peak switch current limit, and thermal protection circuitry.
