EML3290-00SG08NRR
The EML3290 is frequency adjustable, 3A, step-down converter with an integrated high-side and low-side switch. The current mode control is adopted in EML3290 for fast loop response and easy compensation. The EML3290 operates with the wide input voltage from 4.5V to 40V and provides an adjustable output voltage from 0.805V to 30V. The EML3290 features a PWM mode operation with up to 2MHz adjustable switching frequency.
Cycle-by-cycle current limiting, output over-voltage protection and thermal shutdown are provided for fault condition protections. An internal 2ms soft-start design reduces input start-up current and prevents the output voltage and inductor current to overshooting during power-up.
The EML3290 is available in E-SOP-8L with thermally enhanced package.
