Buck DC-DC Converter IC
TCV7103AF
The TCV7103AF is a single-chip buck DC-DC converter IC.
The TCV7103AF contains high-speed and low-on-resistance power
MOSFETs to achieve synchronous rectification using an external low-side
MOSFET, or rectification using an external diode, allowing for high
efficiency.
Features
• Enables up to 6.5A (@ V_IN = 5V)／6A (@ V_IN = 3.3V) of load current
(I_OUT) with a minimum of external components.
• High efficiency: η = 95% (typ.)(@V_IN = 5V, V_OUT = 3.3V, I_OUT = 2A)
(when using the SSM6K411TU as a low-side MOSFET)
HSON8-P-0505-1.27
Weight: 0.068 g (typ.)
• Operating voltage range: V_IN = 2.7V to 5.6V
• Low ON-resistance: R_{DS (ON)} = 0.08Ω (high-side) typical (@V_IN = 5V, Tj = 25°C)
• Oscillation frequency: f_OSC = 1000kHz (typ.)
• Feedback voltage: V_FB = 0.8V ± 1% (@ Tj = 0 to 85 °C)
• Incorporates an N-channel MOSFET driver for synchronous rectification
• 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 (SOP Advance) with a low thermal resistance.
• Soft-start time adjustable by an external capacitor
• Overcurrent protection (OCP) with latch function

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 (1)
to avoid such overloads upon the Product, and (2) 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.
