ADP2323ACPZ Product Details

The switching frequency can be programmed between 250 kHz and 1.2 MHz, or synchronized to an external clock to minimize interference in multirail applications. The dual PWM channels run 180° out of phase, thereby reducing input current ripple as well as reducing the size of the input capacitor.

The bidirectional synchronization pin can be programmed at a 60°, 90°, or 120° phase shift, providing the possibility for a stackable multiphase power solution.

The ADP2323ACPZ can be set to operate in pulse-frequency modulation (PFM) mode at a light load for higher efficiency or in forced PWM for noise sensitive applications. External compensation and soft start provide design flexibility. Independent enable inputs and power good outputs provide reliable power sequencing. To enhance system reliability, the device also includes undervoltage lockout (UVLO), overvoltage protection (OVP), overcurrent pro-tection (OCP), and thermal shutdown (TSD).

The ADP2323ACPZ operates over the −40°C to +125°C junction temperature range and is available in a 32-lead LFCSP_WQ package.
