for a compact, single chip solution. Output currents in
excess of 25 Amps are possible.
Convenient CLK_EN# Signal
Input Under-Voltage Lockout
The IC employs a current mode hysteretic control
mechanism. Inductor current is sensed through a low

±1% DAC Accuracy Over Temperature
Since the error in the output voltage directly sets the
inductor current, the dynamic response to a large,
