An internal resistive divider provides 0.5V reference for the error amplifier, Soft-start (typ. 0.9V) and SCP (typ. 0.8V) circuits. Error amplifier The error amplifier compares a sample of the dc-dc converter output voltage to the 0.5V reference and generates an error signal for the PWM comparator. Output voltage of dc-dc converter is setting with the resistor divider using the following expression (see fig12): R1 Vout = 1 + ∗ 0.5 R2 VOUT R1 Error Amplifier 1 36K R2 0.5V 500 M1815B 8 C1 Figure 12. Error Amplifier with Feedback resistance divider Oscillator The oscillator frequency can be set between 20KHz and 500KHz by connecting a resistor and a capacitor at OSC pin of M1815 B to ground. The oscillator frequency can be determined by using the graph shown in Figure 9. The oscillator output is a sawtooth wave with a minimum value of approximately 0.1V and a maximum value of approximately 0.8V. The PWM comparator compares the oscillator voltage with error amplifier output voltage; internal DTC voltage (typ. 0.6V) and soft start setting voltage. When the sawtooth wave voltage is low than above three-output voltage, the output of M1815 B is high (Turn on NPN transistor or NMOS).

A hysteresis voltage of 200mV eliminates false triggering on noise and chattering. Soft Start/ Short-circuit protection (S.S. / S.C.P.) The soft start is functional after power on, and the interval of soft start time is determined by a capacitor connected to SCP pin (pin 2). When soft start function finished, the internal soft start voltage is setting high, but external SCP pin is setting low in order to change to short circuit detection / protection function. The time of soft start is following expression: Tss = 0.35 ∗ C [µF ] The short circuit protection is functional due to a heavy loading drop and output of error amplifier (COMP pin) is maintain a VPOS (typ. 0.9V), the capacitor is charged until SCP threshold voltage (typ. 0.8V), then M1815 B output is disable (internal pull-low) and the capacitor is discharged to low. The time of short circuit protection is following expression: Tscp = 0.8 ∗ C [µF ] Rev0.6 April 20, 2006 -11- 名通科技有限公司 TEL:0755-86276964 MOB:13570814546 M1815B BOOST CONVERT CONTROL IC Output transistor The M1815 B has a totem-pole transistor with a 40mA source/sink current rating to drive an external NPN transistor or NMOS directly.
