The ADP5041 combines one high performance buck regulator and two low dropout (LDO) regulators in a small 20-lead LFCSP to meet demanding performance and board space requirements. The high switching frequency of the buck regulator enables use of tiny multilayer external components and minimizes board space. When the MODE pin is set to logic high, the buck reg.
Input voltage range: 2.3 V to 5.5 V One 1.2 A buck regulator Two 300 mA LDOs 20-lead, 4 mm × 4 mm LFCSP package Overcurrent and thermal protection Soft start Undervoltage lockout Open-drain processor reset with externally adjustable threshold monitoring Guaranteed reset output valid to VAVIN = 1 V Manual reset input Watchdog refresh input Buck key specifications Output voltage range: 0.8 V to 3.8 V Current mode topology for excellent transient response 3 MHz operating frequency Peak efficiency up to 96% Uses tiny multilayer inductors and capacitors Mode pin selects forced PWM or auto PWM/PSM m.
