EVAL BOARD USER’S MANUAL

Description

This NCV887720 evaluation board provides a convenient

way to evaluate a high frequency boost controller designed

to supply a minimum output voltage during Start-Stop

vehicle battery voltage sags. The unit is in low Iq sleep-mode

under normal battery operating condition and wakes-up

when the monitored voltage drops below 10.65 V and begin

regulating once 10.0 V is reached. Switching frequency is

set to 440 kHz with a user selectable ROSC resistor. The

evaluation board is rated 10.0 V / 2.5 A at a 3.75 V input

voltage. Operation below 3.75 V is possible if output current

is reduced.

Key Features

• Automatic Enable below 10.65 V

• Disable Override Function

• Boost Operation at 10.0 V

• 440 kHz Switching Frequency

• Input Undervoltage Lockout

• Wide Input Voltage of 3.75 V to 45 V

• Low Quiescent Current in Sleep Mode (< 12 mA

Typical)

• Cycle-by-Cycle Current Limit Protection

• Automotive Grade
