Description
General part information
ADP5310 Series
The ADP5310 combines dual buck regulators and one load switch in a 16-lead TSSOP_EP package that meets demanding performance and board space requirements. The device enables direct connection to a wide input voltage range of 2.7 V to 15.0 V, allowing the use of multiple alkaline/NiMH or lithium cells and other power sources.The buck regulator in Channel 1 uses a current mode, constant frequency pulse-width modulation (PWM) control scheme for excellent stability and transient performance, which provides up to 800 mA of output current. The automatic PWM/pulse skipping mode (PSM) control scheme achieves excellent efficiency in light output current. A power-good signal indicates that the output of Channel 1 is within 92% of its nominal value.An ultralow power buck regulator is integrated in Channel 2 with the SYNC/MODE pin to control its operation mode. When SYNC/MODE is set to low, the buck regulator operates in hysteresis mode, which draws only 700 nA of quiescent current to regulate the output under zero load and provides up to 50 mA of output current. Hysteresis mode helps achieve excellent efficiency at less than 1 mW and can work as a keep-alive power supply in a batterypowered system. When the SYNC/MODE pin is set to high, the buck regulator switches to a traditional constant frequency PWM control scheme to provide low output ripple for noise sensitive applications, and the buck regulator provides up to 300 mA of output current in PWM mode.Channel 3 integrates a high-side load switch that operates from 1.65 V to 5.5 V with its input connected to the output of Channel 2. The load switch provides power domain isolation and extends battery operation time.Other key safety features of the ADP5310 include overcurrent protection (OCP), thermal shutdown (TSD), and input undervoltage lockout (UVLO). The ADP5310 is rated for the −40°C to +125°C junction temperature range.ApplicationsEnergy (gas and water) meteringPortable and battery-powered equipmentMedical applicationsKeep-alive power supplies
