BD83070GWL-E2 Power Management ICs - PMIC by Rohm

Synchronous Buck-Boost DC/DC Converter with 2 A Switches (VIN = 2.0 V to 5.5 V, 1ch)

The BD83070GWL was developed to be the de facto standard for low power eco devices used in compact battery-driven applications. Original control technology (X Ramp PWM Control) enables seamless buck-boost transition while built-in low current circuitry achieves an industry-best power conversion efficiency of 97% during operation (200mA load current) along with class-leading 2.8uA current consumption. This contributes to longer operating time in compact battery-driven devices - by as much as 1.14x over standard products during standby (100uA load current).
