This synchronous switching step-up/step-down regulator efficiently produces 5 V from input voltages between 1.4 V and 16 V. (Note: minimum startup voltage is 2.7 V, but it operates down to 1.4 V after that.) Its ability to convert both higher and lower input voltages makes it useful for applications where the power supply voltage can vary greatly, as with batteries that start above but discharge below 5 V. The available output current depends on the input voltage (typically between 1 A and 1.5 A continuous for input voltages close to the output). The regulator also features an optional enable input that can be used to put the regulator in a low-power state with a current draw of less than 15 µA per volt on VIN. The board measures 0.4? × 0.65? and has a typical efficiency of 80% to 90%.

Input voltage: 1.4 V to 16 V (Note: minimum start-up voltage is 2.7 V)
Output voltage: 5 V with 4% accuracy
Typical maximum continuous output current: 1 A to 1.5 A when input voltage is close to the output voltage
Typical efficiency of 80% to 90%, depending on input voltage and load
Under 4 mA typical no-load quiescent current. can be reduced to 10 µA to 15 µA per volt on VIN by disabling the board
Soft-start feature limits inrush current and gradually ramps output voltage
Over-current protection and over-temperature shutoff
Input under-voltage lockout
Power-saving feature maintains high efficiency at low currents
Compact size: 10.2 mm × 16.5 mm × 2.6 mm
Weight: 0.8g. Without headers.

General specifications

Minimum operating voltage: 1.4 V. Note: the minimum startup voltage is 2.7V, but the regulator can operate down to 1.4V after startup.
Maximum operating voltage: 16 V
Continuous output current: 1.5 A. Under typical conditions, where the input voltage is close to the output voltage. Actual achievable continuous output current is a function of input voltage and is limited by thermal dissipation.
Output voltage: 5 V
Reverse voltage protection?: N
Maximum quiescent current: 4 mA. While enabled with no load. Can be reduced to less than 15 µA per volt on VIN using the enable pin
Output type: fixed 5V
