GENERAL DESCRIPTION The ADP2105/ADP2106/ADP2107 are low quiescent current, synchronous, step-down dc-to-dc converters in a compact 4 mm × 4 mm LFCSP_VQ package. At medium-to-high load currents, these devices use a current-mode, constant-frequency pulse width modulation (PWM) control scheme for excellent stability and transient response. To ensure the longest battery life in portable applications, the ADP2105/ADP2106/ADP2107 use a pulse frequency modulation (PFM) control scheme under light load conditions that reduces switching frequency to save power.
Extremely high 97 efficiency Ultralow quiescent current: 20 μA 1.2 MHz switching frequency 0.1 μA shutdown supply current Maximum load current: ADP2105: 1 A ADP2106: 1.5 A ADP2107: 2 A Input voltage: 2.7 V to 5.5 V Output voltage: 0.8 V to VIN Maximum duty cycle: 100 Smoothly transitions into low dropout (LDO) mode Internal synchronous rectifier Small 16-lead 4 mm × 4 mm LFCSP_VQ package Optimized for small ceramic output capacitors Enable/Shutdown logic input Undervoltage lockout Soft start APPLICATIONS Mobile handsets PDAs and palmtop computers Telecommunication/Networking equipment Set top boxes Audio/Video consumer electronics |
