NCP1592

3 V to 6 V Input, 6 A Output

Synchronous Buck PWM

Switcher with Integrated

FETs

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 under−voltage−lockout circuit to prevent start−up

until the input voltage reaches 3 V; an internally or externally

programmable soft−start circuit to limit inrush currents; and a power

good output monitor signal. NCP1592 is available in thermally

enhanced 28−pin TSSOP package.
