REF

The switching PWM controller drives two N-Channel

MOSFETs in a synchronous-rectified buck converter

topology. The synchronous buck converter uses voltage-

mode control with fast transient response. The switching

regulator provides a maximum static regulation tolerance of

±2% over line, load, and temperature ranges. The output is

user-adjustable by means of external resistors down to 0.8V.

PWM Controller Drives Low Cost N-Channel

• 250kHz Constant Frequency Operation

- Both PWM Controllers are Phase Shifted 180°

• Tight Output Voltage Regulation

- All Outputs: ±2% Over Temperature

An integrated soft-start feature brings all outputs into

regulation in a controlled manner when returning to S0/S1

state from any sleep state. During S0 the VIDPGD signal

is within spec and operational.

All outputs, except VDAC, have undervoltage protection.

The switching regulator also has overvoltage and

overcurrent protection. Thermal shutdown is integrated.
