具有跟踪模式的 ADP2120 1.5V、1.25A 降压稳压器的典型应用。 ADP2119/ADP2120 是低静态电流同步降压 DC-DC 稳压器,采用紧凑的 3 mm × 3 mm LFCSP_WD 封装。两款器件均采用电流模式、恒定频率脉宽调制 (PWM) 控制方案,具有出色的稳定性和瞬态响应
说明
Typical Application for ADP2120 1.5V, 1.25A Step-Down Regulator with Tracking Mode. The ADP2119/ADP2120 are low quiescent current, synchronous, step-down dc-to-dc regulators in a compact 3 mm × 3 mm LFCSP_WD package. Both devices use a current mode, constant frequency pulse-width modulation (PWM) control scheme for excellent stability and transient response
