| The ST1S40 device is an internally compensated 850 kHz fixed-frequency PWM synchronous step-down regulator. The ST1S40 operates from 4.0 V to 18 V input, while it regulates an output voltage as low as 0.8 V and up to VIN. The ST1S40 integrates a 95 mΩ high side switch and 69 mΩ synchronous rectifier allowing very high efficiency with very low output voltages. The peak current mode control with internal compensation delivers a very compact solution with a minimum component count. The ST1S40 is available in HSOP-8, VFQFPN 4 mm x 4 mm - 8 lead, and standard SO8 package.3 A DC output current 4.0 V to 18 V input voltage Output voltage adjustable from 0.8 V 850 kHz switching frequency Internal soft-start Integrated 95 mΩ and 69 mΩ Power MOSFETs All ceramic capacitor Enable Cycle-by-cycle current limiting Current fold back short-circuit protection Available in HSOP-8, VFQFPN4x4-8L, and SO8 packages Applications μP/ASIC/DSP/FPGA core and I/O supplies Point of load for: STB, TVs, DVD Optical storage, hard disk drive, printers, audio/graphic cards More information: | | Maximum Output Current: | 3A | Regulator Type: | Linear Voltage | Number of Outputs: | 1 | Output Voltage: | 0.8 → 1.8 V | Line Regulation: | 0.4 % | Load Regulation: | 0.5 Typ.) % | Mounting Type: | Surface Mount | Package Type: | HSOP | Quiescent Current: | 15µA | Pin Count: | 8 | Output Type: | Adjustable | Dimensions: | 5 x 4 x 1.55mm | Height: | 1.55mm | Maximum Input Voltage: | 18 V | Maximum Operating Temperature: | +150 °C |
