PM6680A Dual synchronous step-down controller with adjustable output voltages plus LDO Features 6 V to 36 V input voltage range Adjustable output voltages 5V LDO delivers 100 mA peak current 1.237 V 1 % reference voltage available externally VFQFPN-32 5X5 Current sensing using low side MOSFETs R DS(on) Valley current sensing Description Soft-start internally fixed at 2ms PM6680A is a dual step-down controller Soft output discharge specifically designed to provide extremely high Latched OVP and UVP efficiency conversion, with loss less current Selectable pulse skipping at light loads sensing technique. The constant on-time architecture assures fast load transient response Selectable minimum frequency (33 kHz) in and the embedded voltage feed-forward provides pulse skip mode nearly constant switching frequency operation. An 5mW maximum quiescent power embedded integrator control loop compensates Independent power good signals the DC voltage error due to the output ripple. Pulse skipping technique increases efficiency at Output voltage ripple compensation very light load. Moreover a minimum switching Thermal shutdown frequency of 33 kHz is selectable to avoid audio noise issues. The PM6680A provides a selectable Applications switching frequency, allowing three different values of switching frequencies for the two Embedded computer system switching sections. The output voltages OUT1 FPGA system power and OUT2 can be adjusted from 0.9 V to 5 V and from 0.9 V to 3.3 V respectively. Industrial applications on 24 V High performance and high density DC/DC modules Table 1.
