The LM5168E is an extended temperature range,
(–55°C to +150°C) synchronous buck converter designed to regulate over a wide input
voltage range, minimizing the need for external surge suppression components. A
minimum controllable on time of 50ns facilitates large step-down conversion ratios,
enabling the direct step-down from a 48V nominal input to low-voltage rails for
reduced system complexity and design cost. The LM5168E operates during input voltage
dips as low as 6V, at nearly 100% duty cycle if needed, making the device 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 LM5168E delivers up to 0.3A of output current. A constant on-time (COT) control architecture provides nearly constant switching frequency with excellent load and line transient response. The LM5168E is available in the auto mode version, which enables ultra-low IQ and diode emulation mode operation for high light-load efficiency.
