Overview
Description
The ISL8115EVAL1Z is a synchronous buck converter evaluation board that is used to implement Renesas' ISL8115 wide input range pulse width modulation (PWM) controller. Utilizing voltage mode control with input feed-forward, this board maintains a constant loop gain for an optimal transient response, especially for applications with a wide input voltage range.
Features
- Wide VIN range operation: 2.97V to 36V; up to 5.5V output and 30A load current per phase
- Fast transient response
- Voltage-mode PWM leading-edge modulation with non-linear control
- Input voltage feed-forward
- Integrated 5V high-speed 4A MOSFET gate drivers
- Internal bootstrap diode
- Oscillator programmable from 150kHz to 1.5MHz
- Frequency synchronization to an external clock signal
- Diode emulation mode for light load efficiency improvement
- Output OVP/UVP, OCP and OTP
- Power-good (PGOOD) open drain output
- Adjustable soft-start
- Pre-bias start-up function
- Excellent output voltage regulation
- 0.6V ±1.0% internal reference (-40 °C ~ 125 °C)
- 0.6V ±0.7% internal reference (-40 °C ~ 105 °C)
- Differential voltage sensing
Applications
- Power supply for datacom/telecom and point-of-load (POL)
- Wide input voltage range buck regulators
- High current density power supplies RF power amplifier bias compensation
