LTC3302CRUCM#TRPBF

LTC®3302 is a very small, high efficiency, low noise, monolithic synchronous 2A step-down DC/DC converter operating from a 2.25V to 5.5V input supply. Using constant frequency, and peak current mode control, this regulator achieves fast transient response with small external components. It operates in forced continuous or pulse skipping mode for low noise, or in low-ripple Burst Mode operation for high efficiency at light loads, ideal for battery-powered systems. The IC regulates output voltages as low as 500mV. The adjustable version operates from 500mV to VIN with two additional external resistors. Other features include output overvoltage protection, short-circuit protection, thermal shutdown, clock synchronization, and up to 100% duty cycle operation for low dropout. Application includes optical networking, servers, telecom, automotive, industrial, communications, distributed DC power systems (POL), FPGA, ASIC, µP core supplies.

• Peak current mode control, 27ns minimum on-time, wide bandwidth, fast transient response
• Safely tolerates inductor saturation in overload
• Fixed VOUT range from 0.5V to 3.65V, factory programmed in 50mV steps
• Operating supply voltage range from 2.25 to 5.5V (TA = 25°C, VIN = 4V, VEN = VIN)
• Typical under voltage lockout is 2.1V (VIN rising, TA = 25°C, VIN = 4V, VEN = VIN)
• VOUT accuracy: ±1% overtemperature range, precision 400mV enable threshold
• Typical feedback voltage line regulation is 0.015%/V (VIN = MAX (2.25V, VOUT + 150mV) to 5.5V)
• Typical top switch ON-resistance is 85mohm (TA = 25°C, VIN = 4V, VEN = VIN)
• Frequency synchronization range from -20 to 20% (percentage of nominal frequency range)
• 12-pin FCQFN package, ambient temperature range from -40°C to 125°C
