3 Description
The LM5169 and LM5168 synchronous buck
converters are designed to regulate over a wide input
voltage range, minimizing the need for external surge
suppression components. A minimum controllable on
time of 50 ns facilitates large step-down conversion
ratios, enabling the direct step-down from a 48-V
nominal input to low-voltage rails for reduced system
complexity and solution cost. The LM516x operates
during input voltage dips as low as 6 V, at nearly
100 duty cycle if needed, making it an excellent
choice for wide input supply range industrial and high
cell count battery pack applications.
With integrated high-side and low-side power
MOSFETs, the LM5169 delivers up to 0.65-A of output
current and the LM5168 delivers up to 0.3-A of output
current. A constant on-time (COT) control architecture
provides nearly constant switching frequency with
excellent load and line transient response. The
LM516x is available in FPWM or auto mode versions.
FPWM mode provides forced CCM operation across
the entire load range supporting isolated fly-buck
converter applications. Auto mode enables ultra-low
IQ and diode emulation mode operation for high lightload
efficiency.
