G1513
High Performance Current Mode PWM Controller
ANALOG PWM IC
1.0 General Description
The G1513 is a high performance AC/DC power
supply controller for battery charger and adapter
applications requirements up to 40W.It can meet
less than 80 mW standby power.
G1513 is a current mode PWM controller ,It
operates in fixed frequency which is precisely set
internally. It could operate in Extended Burst
Mode at no load or light load, in which mode
switching loss is minimized and the frequency is
adjusted internally. To ensure that power supplies
work quietly, the frequency is set beyond 22 KHz.
Small current is needed when G1513 starts up
and works, thus a large value resistor could be
used in the startup circuit to minimize the standby
power. Slope compensation circuit is integrated
in G1513, which improves system large signal
stability and reduces the possible sub-harmonic
oscillation at high PWM duty cycle.
Frequency shuffling technique is integrated in
G1513, which helps to achieve excellent EMI
performance.
G1513 offers complete protection functions
including cycle-by-cycle current limiting
protection(OCP), over load protection(OLP),VDD
over voltage protection(OVP), VDD over voltage
clamp and under voltage lockout(UVLO).
The G1513 is available in SOT23-6 package.
