VP3882 Datasheet | Viva Electronics

Description Features The VP3882 is a versatile controller designed for use in Boost and SEPIC power regulator and topologies that needs an external low-side NMOSFET acting as primary switch. Besides cycleby-cycle current limiting, current mode control scheme also makes it wide bandwidth and good transient response. The current limit can be programmed simply with an external resistor. The switching frequency can be set in any value between 100k Hz and 1MHz with a resistor or any external clock source. The VP3882 can be operated at high switching frequency to save the solution board size. It has built-in protection circuits such as thermal shutdown, under-voltage lockout, short circuit protection, and overvoltage protection. Internal soft-start circuitry reduces the inrush current at start-up. - Wide Input Voltage from 2.97V to 60V - Wide Output Voltage up to 80V - Internal 1.275V Reference with ±1.5% Accuracy - Adjustable 100k Hz~1MHz Clock Frequency - I2C Control Interface - Build-in 5V/20m A LDO Regulator - Built-in VBUS Discharging MOSFET for USB PD - 1A Peak Current Limit Using Internal Driver - Current Mode Operation - Internal 4/2Ω MOSFET Switch - External RC pensation - Internal Soft-Start - High Efficiency at Light Loads - Cycle-By-Cycle Current Limit - Over Temperature Protection - Adjustable Input UVLO Threshold Voltage - TQFN-32 5x5 Green Package with Ro HS pliant VP3882 is available in small TQFN-32 5x5 green Applications package. - USB PD Power Controller - Battery Powered Device - Offline Power Supply Typical Application VP3882 Rev P.01 1 http://.viva-elec..tw Functional Block Diagram Preliminary Pin Assignments VP3882 Rev P.01 2 http://.viva-elec..tw Preliminary Pin Descriptions Pin No. 1 2 3 4 5 6 7 8 9 Pin DIS_D DIS_S DIS_G NC NC AGND NC NC...
