GENERAL DESCRIPTION
The ADP3050 is a current-mode monolithic buck (step-down) PWM switching
regulator that contains a high current 1 A power switch and all control,
logic, and protection functions. It uses a unique compensation scheme that
allows the use of any type of output capacitor (tantalum, ceramic,
electrolytic, OS-CON). Unlike some buck regulators, the design is not
restricted to using a specific type of output capacitor or ESR value.
A special boosted drive stage is used to saturate the NPN power switch,
providing a system efficiency higher than conventional bipolar buck switchers.
Further efficiency improvements are obtained by using the low voltage
regulated output to provide the devices internal operating current. A high
switching frequency allows the use of small external surface-mount components.
A wide variety of standard off-the-shelf devices can be used, providing a
great deal of design flexibility. A complete regulator design requires only a
few external components.
The ADP3050 includes a shutdown input that places the device in a low-power
mode, reducing the total supply current to under 20 µA. Internal protection
features include thermal shutdown circuitry and a cycle-by-cycle current-limit
for the power switch to provide complete device protection under fault
conditions.
The ADP3050 provides excellent line and load regulation, maintaining typically
less than ±3% output voltage accuracy over temperature and under all input
voltage and output current conditions.
The ADP3050 is specified over the industrial temperature range of –40°C to
+85°C and is available in a thermally enhanced 8-lead SOIC package.
