FEATURES
Main input voltage range: 2.3 V to 5.5 V Two 800 mA buck regulators and one 300 mA LDO 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 modes BUCK1/BUCK2: output voltage range from 0.8 V to 3.8 V LDO: output voltage range from 0.8 V to 5.2 V LDO: input supply voltage from 1.7 V to 5.5 V LDO: high PSRR and low output noise APPLICATIONS
Power for processors, ASIC, FPGAs, and RF chipsets Portable instrumentation and medical devices Space constrained devices GENERAL DESCRIPTION
When the MODE pin is set low, the buck regulators operate in PWM mode when the load current is above a predefined threshold. When the load current falls below a predefined threshold, the regulator operates in power save mode (PSM) improving the light-load efficiency. Table 1.
