Overview

The LP6470 contains an independent 600KHz constant frequency, current mode, PWM step-down converters. The converter integrates a main switch and a synchronous rectifier for high efficiency without an external Schottky diode. The LP6470 is ideal for powering portable equipment that runs from a 2-cell Lithium-Ion (Li+) battery. The converter can supply 2000mA of load current from a 3.5V to 16V input voltage. The output voltage can be regulated as low as 0.8V. The LP6470 is available in a SOT23-6 package and is rated over the -40℃ to 85℃ temperature range. The LP6470 is a high output current monolithic switch-mode step-down DC-DC converter. The device operates at a fixed 600KHz switching frequency, and uses a slope compensated current mode architecture. This step-down DC-DC converter can supply up to 2A output current at input voltage range from 3.5V to 16V. It minimizes external component size and optimizes efficiency at the heavy load range. The integrated slope compensation allows the device to remain stable over a wider range of inductor values so that smaller values (2.2μH to 10μH) with lower DCR can be used to achieve higher efficiency. The device can be programmed with external feedback to any voltage, ranging from 0.8V to 12V. It uses internal MOSFETs to achieve high efficiency and can generate very low output voltages by using an internal reference of 0.8V. At dropout, the converter duty cycle increases to 95% and the output voltage tracks the input voltage minus the low RDS(ON) drop of the P-channel high-side MOSFET and the inductor DCR. The internal error amplifier and compensation provides excellent transient response, load and line regulation.
