NX7102 Datasheet | Microsemi

DESCRIPTION NX7102 is a 340k Hz fixed The controller is equipped with frequency, current mode, PWM output over-voltage protection which synchronous buck (step-down) DC- protects the IC under an open load DC converter, capable of driving a 3A condition. Additional safety features load with high efficiency, excellent include under voltage lock-out line and load regulation. The device (UVLO), programmable soft-start and integrates N-channel power MOSFET over-temperature protection (OTP) to switches with low on-resistance. protect the circuit. Current mode control provides fast This IC is available in SOIC-8 with transient response and cycle-by-cycle exposed pad package. current limit.
