SP7652ER-L Application Field and Working Principle

SP7652ER-L is a monolithic integrated voltage regulator IC produced by SHARP and categorized under PMIC - Voltage Regulators - DC DC Switching Regulators. It is a low-power, high-output current step-up switching regulator with low on-resistance MOSFET.

The SP7652ER-L uses a switching regulator circuit to maintain the output voltage stable at a pre-set level, no matter how the input voltage, output current or environmental temperature changes. The switching regulator of the SP7652ER-L also has low power consumption and no energy loss, making it suitable for mobile applications.

The SP7652ER-L has wide application fields, such as portable media player, DVD player, and notebook computer. It is also suitable for automotive applications, instrumentation, medical devices and audio systems. This IC is used in low-power steady portable systems due to its low standby current of 5.6uA.

The SP7652ER-L is a low-power two-stage DC-DC step-up regulator integrated IC with built-in N-channel MOSFET. It can build power supply systems up to 8.5V from an input voltage between 2.7V to 10.8V, providing an output current of 600mA maximum. It offers an internal 1.5A sink switch with built-in simple constant-current protection.

The output voltage is mainly adjusted by PWM control, and the oscillator determines the frequency of the PWM signal. The soft start circuit of the built-in clock can suppress inrush current at the start-up.The operating temperature range of the SP7652ER-L IC is -40℃ to +85℃, and the voltage reference of this IC is 1.225V +/- 2%. It also features an over-current protection circuit and a thermal shutdown circuit.

In summary, the SP7652ER-L is a monolithic integrated voltage regulator IC with low standby current and wide application fields, suitable for low-power steady portable systems such as portable media player and DVD player. It has an operating temperature range of -40℃ to +85℃ and provides an output current of 600mA maximum.
