Product Details:

ADP2323为高性能、双通道、Step-down DC-DC regulator，采用电流模式架构。ADP2323集成了两个高端功率型MOSFET开关，和两个低端驱动器，可控制外部N沟道MOSFET。采用两个脉冲宽度调制（PWM）通道，提供3A双路输出，或6A单路交错式输出。支持4.5V至20V输入电源电压范围，输出电压可低至0.6V。

The switching frequency can be set from 250 kHz to 1.2 MHz or synchronized with an external clock to minimize interference in multi-track applications. PWM dual-channel 180° off-phase operation reduces input ripple current and reduces input capacitor size.

The bidirectional sync pins can be configured with 60°, 90°, or 120° phase shifts, providing the possibility to implement stacked multiphase power solutions.

ADP2323 operate in pulse frequency modulation (PFM) mode for higher efficiency at light loads, or in forced PWM mode in noise-sensitive applications. External compensation and soft start provide design flexibility. Independent enable inputs and power-good outputs provide reliable power timing. To improve system reliability, the devices also include undervoltage lockout (UVLO), overvoltage protection (OVP), overcurrent protection (OCP), and thermal shutdown (TSD).

ADP2323 operates over a junction temperature range of -40°C to +125°C and is available in a 32-pin LFCSP_WQ package.
