Product Description

This small synchronous switching step-down (or buck) regulator takes an input voltage of up to 45 V and efficiently reduces it to 3.3 V. The board measures only 0.7? × 0.8? yet delivers typical maximum continuous output currents between 3 A and 4.5 A, depending on the input voltage. An optional enable input can put the regulator in a low-power state with a current draw of 10 µA to 20 µA per volt on VIN. The regulator also features reverse voltage protection and a power-good output that indicates when the regulator cannot adequately maintain the output voltage. The pins have a 0.1? spacing, making this board compatible with standard solderless breadboards and perfboards.

Input voltage: 3.3 V to 45 V (minimum input subject to dropout voltage considerations; see the dropout voltage section for details)
Output voltage: 3.3 V with 4% accuracy
Typical maximum continuous output current: 3 A to 4.5 A (see the maximum continuous output current graph below)
Typical efficiency of 80% to 95%, depending on input voltage, output voltage, and load (see the efficiency graph below)
Very low dropout voltage
Switching frequency: ~700 kHz under heavy loads
Power-save mode that increases light load efficiency by reducing switching frequency
Low quiescent current (see the quiescent current graph below)
Enable input with precise cutoff threshold for disconnecting the load and putting the regulator into a low-power state that draws approximately 10 µA to 20 µA per volt on VIN
“Power good” output indicates when the regulator cannot adequately maintain the output voltage
Frequency spread spectrum operation that lowers peak EMI noise
Under-voltage lockout protection
Soft-start feature limits inrush current and gradually ramps output voltage
Integrated reverse-voltage protection up to 40 V, over-current and short-circuit protection, over-temperature shutoff
Compact size: 0.7? × 0.8? × 0.355? (17.8 mm × 20.3 mm × 9 mm); see the dimension diagram (719k pdf) for more information
Two 0.086? mounting holes for #2 or M2 screws

Dimensions (Without included optional headers.)

Size: 0.7? × 0.8? × 0.345?
Weight: 3.3 g

General specifications

Minimum operating voltage: 3.3 V. Subject to dropout voltage considerations.
Maximum operating voltage: 45 V
Continuous output current: 3.7 A. Typical maximum continuous output current at 30 V in. Actual achievable continuous output current is a function of input voltage and is limited by thermal dissipation.
Output voltage: 3.3 V
Reverse voltage protection?: Y. To -40 V. Connecting supplies over 40 V in reverse can damage the device.
Maximum quiescent current: 9 mA. While enabled with no load. The maximum quiescent current occurs at lower input voltages. It is reduced to under 1 mA with higher inputs or when the regulator is disabled via the enable pin.
