ISL6341B

DATASHEET ISL6341, ISL6341A, ISL6341B, ISL6341C 5V or 12V Single Synchronous Buck Pulse-Width Modulation (PWM) Controller FN6538 Rev 2.00 Dec 2, 2008 The ISL6341, ISL6341A, ISL6341B, ISL6341C makes simple work out of implementing a complete control and protection scheme for a DC/DC stepdown converter driving N-Channel MOSFETs in a synchronous buck topology. Since it can work with either 5V or 12V supplies, this one family of IC’s can be used in a wide variety of applications within a system. It integrates the control, gate drivers, output adjustment, monitoring and protection functions into a single 10 Ld Thin DFN package. The ISL6341, ISL6341A, ISL6341B, ISL6341C (hereafter referred to as “ISL6341x”, except as needed) provides single feedback loop, voltage-mode control with fast transient response. The output voltage can be precisely regulated to as low as 0.8V, with a maximum tolerance of ±0.8% over-temperature and line voltage variations. A fixed frequency oscillator and ...
