* Korean won weakens against dollar

* South Korea benchmark bond yield rises

SEOUL, March 15 (Reuters) - Round-up of South Korean financial markets:

** South Korean shares fell 1% on Friday dragged by stocks in chip and battery firms, after higher-than-expected U.S. inflation tempered interest rate cut bets. The won weakened, while the benchmark bond yield rose.

** The benchmark KOSPI fell 29.31 points, or 1.08%, to 2,689.45 by 0123 GMT, retreating from a 23-month high hit on Thursday.

** The KOSPI was still up 0.4% for the week.

** U.S. producer prices rose 0.6% in February, faster than their gain of 0.3% in January and economists' forecast for 0.3%, data showed on Thursday.

** Among index heavyweights, chipmaker Samsung Electronics fell 1.35% and peer SK Hynix lost 1.17%, while battery maker LG Energy Solution slid 3.37%.

** Their losses tracked the Philadelphia Semiconductor Index's 1.8% fall overnight and U.S. electric-vehicle giant Tesla's 4.2% drop.

** Samsung C&T, de-facto holding company of the Samsung conglomerate, dropped as much as 7.5% from a more than eight-year high, ahead of its annual shareholder meeting at which proposals to raise dividend payouts will be put to a vote.

** Samsung Engineering rose 1.53%, after the construction firm said it won a conditional order worth around $6 billion in the Middle East.

** Of the total 929 traded issues, 305 shares advanced, while 562 declined.
