LвЂ‰DESIGN IDEAS Bidirectional Power Manager Provides
Efficient Charging and Automatic USB
On-The-Go with a Single Inductor
Bidirectional Switching Power
Imagine that your car wonвЂ™t startвЂ”the Path for USB On-The-Go by Sauparna Das Introduction 5.5 The LTC4160 contains a bidirectional
switching regulator between VBUS
and VOUT. When power is applied to
VBUS,the switching regulator acts as
a step down converter and provides
power to the application and battery
charger (Figure 1). The switching
regulator includes a precision average
input current limit with multiple settings. Two of the settings correspond to
the USB 100mA and 500mA limits. The bidirectional switching
regulator is able to power a
portable system and charge
its battery or provide a 5V
output for USB On-The-Go
using a single inductor.
The voltage on VOUT is approximately 300mV above the battery when the
switcher is not in input current limit
and the battery voltage is above 3.3V.
This technique, known as Bat-Track …
