Datasheet Analog Devices ADP5037ACPZ-R7 — 数据表

Dual 3 MHz, 800 mA Buck
Regulators with Two 300 mA LDOs
ADP5037 Data Sheet load is above a predefined threshold, the buck regulators
operate in PWM mode. When the load current falls below a
predefined threshold, the regulator operates in power save
mode (PSM), improving the light-load efficiency. FEATURES
Main input voltage range: 2.3 V to 5.5 V
Two 800 mA buck regulators and two 300 mA LDOs
24-lead, 4 mm × 4 mm LFCSP package
Regulator accuracy: ±1.8%
Factory programmable or external adjustable VOUTx
3 MHz buck operation with forced PWM and auto PWM/PSM
