DETAILED DESCRIPTION
Voltage reference
A 1.25V regulator operating from VCC is used to power the internal circuitry of the M1815B .
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):

Vout = 1 +

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).

BOOST CONVERT CONTROL IC
Under voltage lockout (UVLO)
The under voltage lockout circuits turn the output off and whenever the supply voltage drops
too low (approximately 0.9V at 25℃) for proper operation. 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 ]

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. The driving current capability depends on a resistor
R that is connected to BR/CTL pin (Pin4) of M1815B . (see fig. 14)
