Product Overview
LT8642EV-1#PBF is a synchronous step-down regulator that features Silent Switcher architecture designed to minimize EMI emissions while delivering high efficiency at high switching frequencies. This performance makes the device ideal for noise-sensitive applications and environments. The fast, clean, low-overshoot switching edges enable high efficiency operation even at high switching frequencies, leading to a small overall solution size. Peak current mode control with a 20ns minimum on-time allows high step-down ratios even at high switching frequencies. External compensation via the VC pin allows for fast transient response at high switching frequencies. The VC pin also enables current sharing and a CLKOUT pin enables synchronizing other regulators to the LT8642-1. Applications include server power applications, automotive and industrial supplies, general purpose step-down.
- Silent Switcher® architecture, ultralow EMI emissions, input voltage range from 2.8V to 18V
- External compensation: fast transient response and current sharing
- Forced continuous mode, output soft-start and power good
- VIN quiescent current in shutdown is 0.75µA typ at (VEN/UV = 0V, VIN = 12V, TA = 25°C)
- Feedback pin input current is 20nA maximum at (VFB = 0.6V, TA = 25°C)
- Oscillator frequency is 210KHz typical at (RT = 221K)
- Minimum on-time is 20ns typical at (ILOAD = 3A, SYNC = 2V)
- Top power NMOS on-resistance is 17.5mohm typical at (TA = 25°C)
- Error amp gain is 400V/V typical at (TA = 25°C)
- Operating junction temperature range from -40°C to 125°C, 20-lead LQFN package
