1. Overview
The FA7738N/P is a single-channel step-down DC-DC converter containing power MOSFET.
Featuring a high-withstand-voltage process, this unit is ideally suited for use as a DC-DC converter
with input voltages of up to 45 V and output currents of up to 1.5 A.
The control system is based on current mode, reduces the number of peripheral parts, and achieves a
quick response.
2. Features
- Equipped with single-channel power MOSFET
- Efficiency as high as 85% at an output of 5 V/1.2 A (in a 200-kHz run at power input of 24 V)
- Stable control in current mode
- Switching frequency: 30 kHz to 400 kHz
- ON/OFF function: Current consumption when OFF is 0.1 mA
- Current consumption of the VCC terminal during operation is 0.5 mA
- Well-arranged protection functions:
Overcurrent limitation on the power MOSFET
Soft start (8 ms)
Short-circuit protection of the timer latch (90 ms delay)
Overheat protection
- Package: SOP-8 (E-Pad) / DIP-8
