NCP1592 is a low input voltage 6 A synchronous buck converter
that integrates both 30 mW high side and low side MOSFETs.
NCP1592 is designed for space sensitive and high efficiency
applications. The main features include: a high performance voltage
error amplifier; an undervoltagelockout circuit to prevent startup
until the input voltage reaches 3 V; an internally or externally
programmable softstart circuit to limit inrush currents; and a power
good output monitor signal. NCP1592 is available in thermally
enhanced 28pin TSSOP package.
