1.6A 32V Synchronous Rectified Step-Down Converte
Features 
 
The TD1529 is a monolithic synchronous buck
regulator. The device integrates two 130mΩ
MOSFETs, and provides 1.6A of continuous load
current over a wide input voltage of 4.75V to 32V.
Current mode
control provides fast
transient
response and cycle-by-cycle current limit.
An adjustable soft-start prevents inrush current at
turn-on, and in shutdown mode the supply current
drops to 1µA.
This device, available in an SOP8
package,
provides a very compact solution with minimal external
components.
