Description
General part information
ADP2323 Series
The ADP2323 is a full featured, dual output, step-down dc-to-dc regulator based on current-mode architecture. The ADP2323 integrates two high-side power MOSFETs and two low-side drivers for the external N-channel MOSFETs. The two pulse-width mod-ulation (PWM) channels can be configured to deliver dual 3 A outputs or a parallel-to-single 6 A output. The regulator operates from input voltages of 4.5 V to 20 V, and the output voltage can be as low as 0.6 V.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 ADP2323 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 ADP2323 operates over the −40°C to +125°C junction temperature range and is available in a 32-lead LFCSP_WQ package.APPLICATIONCommunication infrastructureNetworking and serversIndustrial and instrumentationHealthcare and medicalIntermediate power rail conversionDC-to-dc point of load applications
