GENERAL DESCRIPTION

PT4201 is a current mode HB LED driver

controller， designed to drive HB LED lighting

systems from 1W through 30W. The LED lighting

systems based on the PT4201 enjoys the

advantages of high current accuracy, high

efficiency, low external component count and low

EMI. The PWM switching frequency at normal

operation

trimmed to a tight range. The built in LEB on the

current sense input efficiently removes the signal

glitch due to snubber circuit diode reverse

recovery and will greatly reduce the external

component count and system cost in the design.

Rich protection is implemented in PT4201

including cycle-by-cycle current limiting (OCP),

over load protection (OLP), VDD over voltage

clamp and under voltage lockout (UVLO). Gate

drive output is clamped at 18V to protect the

power MOSFET.

Excellent EMI performance is achieved with

C.R.PowTech proprietary frequency Jittering

technique together with soft driving control at

totem pole gate drive output. The PT4201 also

provides short circuit protection which shuts

down the system when short circuit occurs.

The PT4201 is available in SOT23-6

externally

programmable

PT4201

packages.
