The devices operate with PFM (Pulse Frequency Modulation) mode at light load current, and PWM (Pulse Width Modulation) mode at heavy load current. An operation mode is automatically switched depending on load current. When a bottom of inductor ripple current is under 0A, reverse current flow at low-side N-channel MOSFET of output block. The devices operate with PFM mode during detecting this current. A current of switching PFM / PWM mode (Ichange) is calculated by an equation below. L : inductance, fSW : 1.1MHz Switching voltage RAA23014x RAA23015x Reverse current detect Reverse current Inductor current Reverse current flow when a bottom of inductor ripple current is under 0A. RAA23014x has x_autoPFM pin. When Low level, the devices operate Auto PFM mode (PFM mode / PWM mode changed automatically). When High level, the devices operate PWM mode, then not change into Auto PFM mode. RAA23015x operates only Auto PFM mode.

When EN pin is set from low level to high level, the device starts operation and output voltage rises with soft start. Soft start time are fixed at 2ms(Typ.) and no additional components are needed. Soft start feature gradually increases the error amplifier (E/A) input threshold voltage by using the voltage that is generated by the digital soft start (DSS) circuit.

When an EN pin is changed from high level to low, discharge switch in VOUT pin is turned on and all capacitors which are connected to DC/DC output are rapidly discharged through VOUT pin. When VIN pin voltage becomes low level, discharge switch become off because there are no voltage to keep them on. The control voltage of discharge switches is VREG, and the discharge time of VREG capacitor is over 100ms when VIN voltage falls down, so even if EN pin is connected to VIN pin, output voltage can be discharged because VREG voltage level can keep the discharge switches on. When VREG voltage falls under 3.7V(typ.), VOUT pin becomes high impedance. Discharge time can be calculated by an equation below. Vdc is a voltage after tdc(s). CALL is sum of all capacitance which are connected to output (output capacitor, bypass capacitor around MCU, etc.). Rondc is on resistance of discharge circuit.

The circuit can be easily designed by RAA23014x without two diodes. When DC/DC operates, VBB_OUT = VOUT. When DC/DC stops and VOUT pin voltage is higher than VBB_IN pin, VBB_OUT = VOUT pin. When DC/DC stops and VOUT pin voltage is lower than VBB_IN pin, VBB_OUT = VBB_IN pin. VBB_OUT voltage value is dependent on on-resistance between VBB_IN and VBB_OUT, On-resistance between VOUT and VBB_OUT and VBB_OUT output current. VBB_OUT can be calculated by equations below. 1. Normal operation mode (VBB_OUT = VOUT) 2. Battery backup mode (VBB_OUT = VBB_IN) VBB_OUT : VBB_OUT voltage (V) VOUT : VOUT voltage = DC/DC output voltage (V) VBB_IN : VBB_IN voltage = Battery voltage (V) IBB_OUT : VBB_OUT output current (A) Ron_vout : On resistance between VOUT and VBB_OUT 100Ω (Typ.)

If this voltage falls below the input detection voltage (0.35V(typ.)) of the short circuit protection, the output are stopped (latched to OFF). At this time, common circuits (such as the internal power supply block, etc.) continue operating. When the protection is operating, to reset the latch, either turn the EN pin from high to low or drop the VIN pin voltage under operation stop voltage of UVLO. Thermal Shutdown Circuit (Auto Recovery Type) When overheating has been detected (detect temperature: 165°C ), the output is stopped. Then, power MOSFET of output both high side and low side are turned off. Common circuits (such as the internal power supply block, etc.) continue operating. If the device temperature falls and becomes under detect temperature, the protection is canceled and output automatically resumes. Under Voltage Lockout Circuit (Auto Recovery Type) (1) Under voltage lockout operation When the power supply voltage (VIN) falls to the operation stop voltage (3.7V(typ.)), output from all channels stops. Common circuits (such as the internal power supply block, etc.) continue operating. (2) Restoring output Once VIN is restored to the Operating start voltage (3.9V(typ.)), the under voltage lockout operation is canceled and output automatically resumes. The output voltage cannot be restored while the under voltage lockout circuit is operating, not even by manipulating the EN pin. Current Limiting If an overcurrent occurs, an output current is limited on a pulse-by-pulse basis. If the current sensor detects an overcurrent, the current is limited and the switching operation of the Power MOSFET in the output stage stops until the next cycle. When an output current is limited, the output voltage drops. If a FB pin voltage falls below the input detection voltage, the short-circuit protection circuit starts operating.

When ∆IL increases, inductor current peak raises, so ripple of Vout gets larger and power loss increases. But, large size inductor is required to lower ∆IL. ∆IL can be calculated by an equation below. fsw is 1.1MHz. Peak current of inductor (ILpeak) can be calculated by an equation below.
