ADP2371ACPZ Product Details

The ADP2370/ADP2371ACPZ are high efficiency, low quiescent current, 800 mA buck (step-down) dc-to-dc converters in small 8-lead, 3 mm × 3 mm LFCSP (QFN) packages. The total solution requires only three tiny external components.

The buck regulator uses a proprietary high speed current mode, constant frequency PWM control scheme for excellent stability and transient response. The need for an external rectifier is eliminated by using a high efficiency synchronous rectifier architecture.

To ensure the longest battery life in portable applications, the ADP2370/ADP2371ACPZ employ a power saving variable frequency mode that reduces the switching frequency under light load conditions. The ADP2370/ADP2371ACPZ operate from input voltages of 3.2 V to 15 V allowing the use of multiple alkaline/NiMH, lithium cells, or other standard power sources.

The ADP2370/ADP2371ACPZ offer multiple options for setting the operational frequency. The ADP2370/ADP2371ACPZ can be synchronized to a 600 kHz to 1.2 MHz external clock or it can be forced to operate at 600 kHz or 1.2 MHz via the FSEL pin. The ADP2370/ ADP2371ACPZ can be forced to operate in PWM mode (FPWM) when noise considerations are more important than efficiency.

A power-good output is available to indicate when the output voltage is below 92% of its nominal value.

The ADP2371ACPZ is identical to the ADP2370 except that the ADP2371ACPZ includes the addition of an integrated switched resistor, quick output discharge function (QOD) that automatically discharges the output when the device is disabled.

Both devices include an internal power switch and a synchronous rectifier for minimal external part count and high efficiency. The ADP2370/ADP2371ACPZ also include internal soft start and internal compensation for ease of use.

During a logic controlled shutdown, the input is disconnected from the output and the regulator draws less than 1.2 μA from the input source. Other key features include undervoltage lockout to prevent deep battery discharge and soft start to prevent input overcurrent at startup. Short-circuit protection and thermal overload protection circuits prevent damage under adverse conditions.

The ADP2370/ADP2371ACPZ each use one 0805 capacitor, one 1206 capacitor, and one 4 mm × 4 mm inductor. The total solution size is about 53 mm2 resulting in a very small footprint solution to meet a variety of portable applications.
