Product Details
The ADP2441/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.
The ADP2442 offers the flexibility of external clock synchronization. The switching frequency can be synchronized to an external clock, applied to the SYNC/MODE pin. The ADP2442 can also be configured to operate in the forced fixed frequency mode for low EMI or power saving mode to reduce the switching losses at light load.
The ADP2442 uses hiccup mode to protect the IC from short circuits or from overcurrent conditions on the output. The internal soft start limits inrush current during startup for a wide variety of load capacitances. Other key features include input undervoltage lockout (UVLO), thermal shutdown (TSD), and precision enable (EN), which can also be used as a logic level shutdown input.
The ADP2442 is available in a 3 mm × 3 mm, 12-lead LFCSP package and is rated for a junction temperature range from −40°C to +125°C.
