TCV7106FN
Buck DC-DC Converter IC
The TCV7106FN is a single-chip buck DC-DC converter IC.
The TCV7106FN contains high-speed and low-on-resistance power
MOSFETs for the main switch and has switchable operation mode,
synchronous and non-synchronous. So the TCV7106FN can achieve
high efficiency in the large load current range.
Features
• Enables up to 2.5A (@ V_IN = 5V) ／2A (@ V_IN = 3.3V) of load
current (I_OUT) with a minimum of external components.
• High efficiency: η = 95% (typ.)
Weight: 0.017 g (typ.)
(synchronous mode @V_IN = 5V, V_OUT = 3.3V, I_OUT = 0.7A)
• High efficiency in the large load current range is realized because of switchable operation mode, synchronous and
non-synchronous.
• Operating voltage range: V_IN = 2.7V to 5.6V
• Low ON-resistance: R_{DS (ON)} = 0.18Ω (high side) / 0.12Ω (low-side) typical (@V_IN = 5V, T_j = 25°C)
• Oscillation frequency: f_OSC = 550kHz (typ.)
• Feedback voltage: V_{FB =} 0.8V ± 1% (@T_j = 0 to 85°C)
• Uses internal phase compensation to achieve high efficiency with a minimum of external components.
• Allows the use of a small surface-mount ceramic capacitor as an output filter capacitor.
• Housed in a small surface-mount package (PS-8) with a low thermal resistance.

This product has a MOS structure and is sensitive to electrostatic discharge. Handle with care.
The product(s) in this document (“Product”) contain functions intended to protect the Product from temporary
small overloads such as minor short-term overcurrent, or overheating. The protective functions do not necessarily
protect Product under all circumstances. When incorporating Product into your system, please design the system to
avoid such overloads upon the Product, and to shut down or otherwise relieve the Product of such overload conditions
immediately upon occurrence. For details, please refer to the notes appearing below in this document and other
documents referenced in this document.
