SLM27211
SLM27211 is High-Frequency High-Side and Low-Side Driver manufactured by Sillumin.
SLM27211 120-V, 4-A Peak, High-Frequency High-Side and Low-Side Driver
GENERAL DESCRIPTION
The SLM27211 is a high-frequency N-channel MOSFET driver include a 120V bootstrap diode and high-side and low-side drivers with independent inputs for maximum control flexibility. This allows for N-channel MOSFET control in half-bridge, full-bridge, two-switch forward, and active clamp forward converters. The low-side and the high-side gate drivers are independently controlled and matched to 2ns between the turn on and turn off of each other.
An on-chip bootstrap diode eliminates the external discrete diodes. Under voltage lockout is provided for both the high-side and the low-side drivers forcing the outputs low if the drive voltage is below the specified threshold. TYPICAL APPLICATIONS
- Power supplies for tele, Data, and merchant
- Half-Bridge and Full-Bridge converters
- Push-Pull converters
- High voltage synchronous-buck converters
- Two-Switch forward converters
- Active-Clamp forward converters
- Class-D audio amplifiers
