The ADP2442 is a constant frequency, current mode control,
synchronous, step-down, dc-to-dc regulator that is capable of
driving loads of up to 1 A with excellent line and load regulation
characteristics. The ADP2442 operates with a wide input voltage
range from 4.5 V to 36 V, which makes it ideal for regulating
power from a wide variety of sources. In addition, the ADP2442
has very low minimum on time (50 ns) and is, therefore, suitable
for applications requiring a very high step-down ratio.
The output voltage can be adjusted from 0.6 V to 0.9 × VIN. High
efficiency is obtained with integrated low resistance N-channel
MOSFETs for both high-side and low-side devices.
The switching frequency is adjustable from 300 kHz to 1 MHz with
an external resistor. The ADP2442 also has an accurate power-good
(PGOOD) open-drain output signal. C1
