DESCRIPTION
The SC1101 is a versatile, low-cost, voltage-mode
PWM controller designed for use in single ended DC/
DC power supply applications. A simple, fixed-voltage
buck regulator can be implemented using the SC1101
with a minimum of external components. Internal level
shift and drive circuitry eliminates the need for an ex-
pensive p-channel, high-side switch. The small device
footprint allows for compact circuit design.
SC1101 features include a temperature compensated
voltage reference, triangle wave oscillator, current limit
comparator, frequency shift over-current protection,
and an internally compensated error amplifier. Pulse by
pulse current limiting is implemented by sensing the
differential voltage across an external resistor, or an
appropriately sized PC board trace.
The SC1101 operates at a fixed frequency of 200kHz,
providing an optimum compromise between efficiency,
external component size, and cost.
