ST1S12GR, Synchronous rectification

ST1S12XX ST1S12XX12, ST1S12XX18 Synchronous rectification with enable, 0.7 A, 1.7 MHz fixed or adjustable step-down switching regulator in TSOT23-5L F

Features

* Step-down current mode PWM (1.7 MHz) DCDC converter 3% DC output voltage tolerance Synchronous rectification Fixed output voltage 1.2 V, 1.8 V, and ADJ (available on request 1.5 V, 2.5 V and 3.3 V) Enable function Interna

Applications

* and, generally, to replace the high current linear solution when the power dissipation may cause high heating of the application environment. It provides up to 0.7 A over an input voltage range of 2.5 V to 5.5 V. A high switching frequency (1.7 MHz) allows the use of tiny surface-mount components. I
