General Description
The H68 50 is a highly integrated low cost
current mode PWM controller, which is ideal
for small power cur rent mode of of fline
AC-DC fly- back converter applic ations.
Making use of external resistors, the IC
changes the operating frequency and
automatically enters the PFM/CRM ( Cycle
Reset Mode) und er light-load/zer o-load
conditions. This can minimize standby
power consumption and achieve powe r-
saving functions. With a very lo w st art-up
current, the H685 0 could use a large value
start-up resistor (2M).
Built-in synchronized slo pe compens ation
enhances the st ability of the syste m and
avoids sub-harmonic oscillation. D ynamic
peak current limiting circuit minimizes output
power chang e caused by delay time of the
system over a universal AC input range.
Leading edge blanking circuit on current
sense input could remove the signal glitch
due to snubber circuit diode reverse
recovery and thus greatly reduces the
external component count and system cost
in the design. Cycle-by-Cycle current
limiting ensures safe operation even during
short-circuit.
Excellent EMI performance is achieved
built-in soft driver and low EMI technique.
The H68 50 offers perfect protection like
OVP(Over Voltage Prote ction)OLP(Over
Load Protection) SCP(Short circuit
protection)OTPSense Fault Protection
and OCP(Over current protection). The
H6850’s output driver is soft clamped to
maximum 18.0V to protect the power
MOSFET. H6850 is offered in SOT-23-6L,
SOT-8 and DIP-8 packages.
