MaxLinear SP6652

1A, High Efficiency, Fixed 1.4 MHz Current Mode PWM Buck Regulator

Overview

TopologyBuck Converter
Input voltage2.7-5.5 V
Switching frequency1200-1600 kHz
Output 13.3 V / 1 A
IC revisionJ

Description

The SP6652 is a high efficiency, synchronous buck regulator ideal for portable applications using one Li-Ion cell, with up to 1A of output current. The 1.4MHz switching frequency and PWM control loop are optimized for a small value inductor and ceramic output capacitor, for space constrained portable designs. In addition, the input voltage range of 2.7V to 5.5V; excellent transient response, output accuracy, and ability to transition into 100% duty cycle operation -- further extending useful battery life -- make the SP6652 a superior choice for a wide range of portable power applications. A logic level shutdown control, external clock synchronization, and forced-PWM or automatic control inputs are provided. Other features include soft-start, over current protection and 140ºC over-temperature shutdown.
