NCP1596, NCP1596A Product Preview 1.5 A, 1.5 MHz Current Mode PWM Buck Down Converter http://onsemi.com The NCP1596/NCP1596A is a current mode PWM buck converter with integrated power switch. It can provide up to 1.5 A output current with high conversion efficiency. High frequency PWM control scheme can provide a low output ripple noise. Thus, it allows the usage of small size passive components to reduce the board space. In a low load condition, the controller will automatically change to PFM mode which provides a higher efficiency at low load. Additionally, the device includes soft−start, thermal shutdown with hysteresis, cycle−by−cycle current limit, and short circuit protection.

Slope compensation consists of a ramp signal generated by the synchronization block and adding this to the inductor current signal. The summed signal is then applied to the PWM comparator. The NCP1596 is a current−mode buck converter with switching frequency at 1.5 MHz. High operation frequency can reduce the capacitor value and PCB area. Also, more features are built in this converter. 1. Internal 1 ms soft−start to avoid inrush current at startup. 2. Internal cycle by cycle current limit provides an output short circuit protection. 3. Internal compensation. No external compensation components are necessary. 4. Thermal shutdown protects the devices from over heat. 5. 100% duty cycle allowed. Speed up transient load response. The upper feature can provide more cost effective solutions to applications. A simple function block diagram and timing diagram are shown in Figure 1 and Figure 2. Thermal Shutdown Internal Thermal Shutdown circuitry is provided to protect the integrated circuit in the event when maximum junction temperature is exceeded. When activated, typically at 180°C, the shutdown signal will disable the P−channel switch. The thermal shutdown circuit is designed with 30°C of hysteresis. This means that the switching will not start until the die temperature drops by this amount. This feature is provided to prevent catastrophic failures from accidental device overheating. It is not intended as a substitute for proper heat sinking. NCP1596 is contained in the thermally enhanced QFN package. Under Voltage Lockout (UVLO) Soft−Start and Current Limit UVLO function is used to ensure the logic level correctly when input voltage is very low. In NCP1596, the UVLO level is set to 3.5 V. If the input voltage is less than 3.5 V, the converter will shutdown itself automatically. A soft start circuit is internally implemented to reduce the in−rush current during startup. This helps to reduce the output voltage over−shoot. The current limit is set to allow peak switch current in excess of 2 A. The intended output current of the system is 1.5 A. The ripple current is calculated to be approximately 350 mA with a 3.3 mH inductor. Therefore, the peak current at 1.5 A output will be approximately 1.7 Amps. A 2.5 Amp set point will allow for transient currents during load step. The current limit circuit is implemented as a cycle−by−cycle current limit. Each on−cycle is treated as a separate situation. Current limiting is implemented by monitoring the P−channel switch current buildup during conduction with a current limit comparator. The output of the current limit comparator resets the PWM latch, immediately terminating the current cycle. When output loading is short circuit, device will auto restart with soft start. Low Power Shutdown Mode (EN) NCP1596A can be disabled whenever the EN pin is tied to ground. During the shutdown mode, the internal reference, oscillator and driver control circuits will be turn off, the device only consume 1 mA typically and output voltage will be discharge to zero by the external resistor divider. EN pin has an internal pull−up current source, which typical value is 500 nA. Power Saving Pulse−Frequency−Modulation (PFM) Control Scheme While the converter loading decreases, the converter enters the Discontinues−conduction−mode (DCM) operation. In DCM operation, the on−time (Ton) of the integrated switch for each switching cycle will decrease when the output current decreases. In order to maintain a high converter efficiency at light load condition. A minimum Ton is set to 70 ns. It can make sure a minimum fixed power send to output. To avoid a higher switch loss occurs when without loading apply. This control scheme can reduce the switching loss at light load and improve the conversion efficiency. Error Amplifier and Slope Compensation A fully internal compensated error amplifier is provided inside NCP1596. No external circuitry is needed to stabilize the device. The error amplifier provides an error signal to the PWM comparator by comparing the feedback voltage (800 mV) with internal voltage reference of 1.2 V. Current mode converter can exhibit instability at duty cycles over 50%. A slope compensation circuit is provided http://onsemi.com 10 NCP1596, NCP1596A APPLICATION INFORMATION Output Voltage Selection ripple current, input voltage, output voltage, output current and operation frequency, the inductor value is given by: The output voltage is programmed through an external resistor divider connect from VOUT to FB then to GND. For internal compensation and noise immunity, the resistor from FB to GND should be in 10 k to 20 k ranges. The relationship between the output voltage and feedback resistor is given by: V OUT + V FB ǒ1 ) R1Ǔ D IL + ǒ1 * VV Ǔ OUT F SW (eq. 2) IN DIL : peak to peak inductor ripple current L: inductor value FSW: switching frequency After selected a suitable value of the inductor, it should be check out the inductor saturation current. The saturation current of the inductor should be higher than the maximum load plus the ripple current.

D IL(MAX) + D IOUT(MAX) ) Input Capacitor Selection DIL(MAX) DIOUT(MAX) In the PWM buck converter, the input current is pulsating current with switching noise. Therefore, a bypass input capacitor must choose for reduce the peak current drawn from the power supply. For NCP1596, low ESR ceramic capacitor of 10 mF should be used for most of cases. Also, the input capacitor should be placed as close as possible to the VCCA pin for effective bypass the supply noise. D IL (eq. 3) 2 : Maximum inductor current : Maximum output current Output Capacitor Selection Output capacitor value is based on the target output ripple voltage. For NCP1596, the output capacitor is required a ceramic capacitors with low ESR value. Assume buck converter duty cycle is 50%. The output ripple voltage in PWM mode is given by: Inductor Selection The inductor parameters are including three items, which are DC resistance, inductor value and saturation current. Inductor DC resistance will effect the convector overall efficiency, low DC resistor value can provide a higher efficiency. Thus, inductor value are depend on the inductor D VOUT [ D IL ǒ4 1 FSW C OUT Ǔ ) ESR (eq. 4) In general, value of ceramic capacitor using 20 mF should be a good choice.
