Description

General part information

LM2103 Series

The LM2103 is a compact, high-voltage gate driver designed to drive both the high-side and the low-side N-channel MOSFETs in a synchronous buck or a half-bridge configuration. The INL inverting input allows the driver to be used in either dual or single PWM input applications.

The fixed dead-time and the –1-V DC and –19.5-V transient negative voltage handling on the SH pin improve the system robustness in high noise applications. The LM2103 is available in an 8-pin SOIC package compatible with industry standard pinouts. Undervoltage lockout (UVLO) is provided on both the low-side and the high-side power rails for protection during power up and power down.
