SG3845D Description

Short technical summary and product information.

The SG3845D from Microchip Technology is a DC DC Switching Controller featuring a current mode PWM architecture. It is designed for step-up and step-down voltage conversion functions, with an output type of Transistor Driver. The device supports a wide input voltage range from 7.6V to 30V and operates at frequencies between 100Hz and 500kHz, with a maximum duty cycle of 48%.

 

This controller is suitable for applications requiring positive output configurations that are isolation capable. It features a synchronous rectifier and operates with a single output phase. The operating temperature range is from 0°C to 70°C (Ambient Temperature). The SG3845D is supplied in an 8-SOIC package, suitable for surface mount applications.

 

Key electrical characteristics include its 7.6V to 30V operating voltage, 100Hz to 500kHz frequency range, and a maximum duty cycle of 48%. The topology used is Flyback, and it is not clock synchronous. The component is RoHS3 compliant and has a Moisture Sensitivity Level (MSL) of 1.
