ADP5310AREZN-R7 General Description

The ADP5310 combines dual buck regulators and one load switchin a 16-lead TSSOP_EP package that meets demanding performanceand board space requirements. The device enables directconnection to a wide input voltage range of 2.7 V to 15.0 V, allowingthe use of multiple alkaline/NiMH or lithium cells and otherpower sources.

Key Features

Wide input voltage range: 2.7V to 15.0 V
700 nA quiescent current when EN1 = SYNC/MODE = low
±1.5% output accuracy over full temperature range in PWM mode
600 kHz (or 1.2 MHz) switching frequency with optional synchronization input from 400 kHz to 1.4 MHz
Channel 1: 800 mA buck regulator
- Automatic PSM/PWM or forced PWM mode via factory fuse
- 100% duty cycle operation mode
- Adjustable/fixed output options via factory fuse
- Power-good flag

Application

Energy (gas and water) metering
Portable and battery-powered equipment
Medical applications
Keep-alive power supplies
