FA3629AV
s Description
FA3629AV is a Power IC which includes DC-DC
converter controller and Nch-power MOSFET.
This IC can directly drive Nch/Pch MOSFET.
This IC is suitable to reduce converter size because it has
many functions in a small package TSSOP.
s Features
• Low input voltage: 2.5V to 6.5V
• 40V CDMOS Process:
Built-in 0.3Nch-Power MOSFET(ch1, open drain)
• 3-channels PWM Control:
2 boost circuits(ch1, ch2), 1 inverting circuit (ch3)
• Adjustable soft start time and maximum duty cycle
• Built-in timer latch for short circuit protection:
Delay time = 216 / (switching frequency)
• Built-in protection functions: Overcurrent limit for MOSFET,
overheat protection, undervoltage lockout
• Wide range of operation frequency: 100kHz to 1MHz
• Package: TSSOP-16(Thin and small)
s Applications
• Power supply for general equipment
